Thank you for doing all of this meticulous research. Your patience and determination are evident, and it pleases me to see it focused on a young man’s efforts whom I admire very very much.
First time viewing one of your videos and know nothing yet of this kind of process but that handwriting is something I could only dream of haha. Good video man, a very fluent way to inspire people to understand new things.
Great testing and video, makes me think about this box of ore I got from him as well. And how to process it. I remember watching his test. And he had about 1ozt per ton. So it can definitely be wildly different per test. Or even cheery picked for what he wanted to test. Or even that one rock.
As a Geochemist with 33 years of experience in the field, I have to say I like your procedural processes, keeping track of everything. Now I'll give you two bits of advice. The moment you introduce the word "pan" into the concentration process, you are shooting yourself in the foot when it comes to fine gold and second, bismuth requires lower temps in the cupellation oven which creates other issues with the digestion of the various oxides. There is a reason that every ISO qualified assay lab in the world uses lead as a collector metal. Best of luck from a new subscriber! *Edit You have got to get yourself a riffle splitter. All that mixing and dividing with a sheet of brass...Just shovel it in. They are hard to find. Mine are hand made.
Hi Rockbutcher. Yes, at the moment I've abandoned Bismuth because I can't get it to work reliably at any cupellation temperature. I agree with you about panning; I can't get consistent results to the accuracy that I'm looking for. Thanks for the comments, very useful.
@@orophilia Thanks. The QA/QC thing is a rabbit hole that will swallow you whole. I've been down it several times and every time the result is, "Trust your lab." LOL That stuff from Jason looks to be mostly fine gold, so a statistical split of say a 1kg sample to a 30 or 50g charge should give you a pretty accurate result. Three runs of the same mass of the same sample will tighten up your result. My problem is that a lot of the lode gold that I'm involved with can be quite coarse, which means that even when split well, the fraction that gets pulverised and fired may not contain the one or two 'nuggets' that are present in the sample. Then we have to re-split the crush and re-pulverise another until we get a result. This is why I have no hair left!🤣
Very interesting. I have a box of the same ore that I haven’t processed yet. Although, I did pan the sand that came with ore. Found a small amount of free mill gold. After seeing your video, might re-pan tailings and dissolve heavies in AR to check for gold (with stannous chloride test).
@@orophilia I have played around with extracting gold from rocks enough to appreciate how very true your comment is! It can also be extremely hazardous. Most don't understand the dangers of using AR and home made melting furnaces.
Great video, I bought a bag of ore and I could only find a couple visible pieces but under magnification I could see more. I crushed some with a 20 ton press into a super fine powder, I started running in a blue bowl but that washed the gold away, I think it would wash threw a sluice too I bet even Jason's shaker table is loosing some. In the pan the only time I can see it is when it congregates together and I have done a second pan of some of it and still find gold this stuff is super fine. I have maybe a quarter gram in a vial of water and it has a dull brownish look not the bright gold foil look. Another observation is my bag has a allot of reddish dust where I did not see that with yours I'm thinking my bag came more from the floor of the mine than the wall because I also found a small piece of dry rotted wood with a piece of a nail in it and a couple small rocks that have pebbles stuck to them with what appears to be rusty metal. I have a second bag but only looked at the big rocks and it appears about the same as the first bag.
Hey Dave just an idea……but if you were to take some stainless steel welding rods and just welded slag onto the ends of the carabiners, it would harden it EXTREMELY hard and give a much longer life to the use of them.
Thanks for doing this video. I too purchased a couple of bags from Jasons mine. Different material. I am not through all of it yet but the e gold is so small I need a loop to see it. I don't look to get much but it is an experience doing it.
I'd be interested to see if Keith Bowen's technique for fine particles and a finishing pan yielded more gold for the chemical assay. Great video. Thank you for sharing
In the final analysis it is the first analysis that counts. Thank you for your showing various methods, I really like bismuth, fire assaying is such an art. Yes I agree that the ore may have some platinum mineral. or iron. Do you actually need more heat for the bismuth to release the gold. Often looking at the bead if it is mossy looking I mean fuzzy it often has platinum. Color of the cupel might also give some indication. Think you are on the right track.
If bismuth is being substituted for lead in the cupellation process, it represents a significant departure from traditional methods, as lead is typically the primary metal oxidized and absorbed into the cupel during cupellation. However, using bismuth instead of lead could be done under specific circumstances, such as when lead is unavailable or undesirable due to environmental or health concerns. When substituting bismuth for lead in the cupellation process, the optimal temperature may vary compared to traditional cupellation with lead. Bismuth has a lower melting point (271.4°C or 520.5°F) compared to lead, which melts at 327.5°C (621.5°F). However, bismuth also has a relatively high boiling point of 1560°C (2840°F). When bismuth is added to the cupellation process, it's usually in small quantities and primarily to aid in the separation of precious metals from lead. The addition of bismuth alters the properties of the lead oxide formed during cupellation, making it easier for the lead oxide to be absorbed into the cupel. However, the optimal temperature for cupellation when bismuth is used would typically fall within the same range as when it is not used, which is approximately 950°C to 1050°C (1742°F to 1922°F). Traditional smelting processes often result in environmental pollution due to the release of harmful gases such as sulfur dioxide (SO₂) into the atmosphere. To address this issue, a closed-system approach is proposed, wherein sulfide ores are roasted in the presence of excess iron(III) oxide (Fe₂O₃) eliminating the need for an external oxidizing atmosphere. The controlled atmosphere system captures gases produced during roasting, directing them to a collection chamber equipped with gas collection mechanisms. Captured gases, including sulfur dioxide, can undergo further treatment for impurity removal and recovery of valuable components. This approach offers a sustainable solution for metal extraction, minimizing environmental emissions and promoting responsible resource management in the mining industry. The proposed system draws inspiration from retort-like designs, tailored to meet the specific requirements of sulfide ore processing. Through careful design and optimization, this integrated approach holds promise for advancing environmentally friendly practices in metal extraction while meeting the growing demand for sustainable mining technologies. In the presence of excess iron(III) oxide (Fe₂O₃), sulfide ores can indeed undergo a different reaction pathway during roasting compared to traditional smelting processes. Instead of forming iron sulfide (FeS), which can be undesirable due to its potential interference with subsequent refining processes, the excess iron(III) oxide can promote a more favorable reaction. ...so maybe breaking down the sulfides as such is a good first step, and then run that through the blue bowl again, and a magnetic separator too, because the iron is still present.
@@JohnViinalass-lc1ow So, in essence, bismuth acts like a chill buddy for lead, calming down its tendency to go all gassy at high temps, thereby keeping your precious metals grounded, quite literally. It's like using a heavy blanket on a restless sleeper; it keeps everything in place, ensuring that the lead does its job without sending your silver and gold on an unintended skyward journey. ~ CHEERS
I had the same problem cuppelling with bismuth. I just end up with microscopic balls of gold all over. I'll be sticking with using lead. Interestingly enough, my findings from a 12 kg bag of Jason's "run of the mine" ore returned a result of 7.17 grams per short ton
In Jason‘s last video, he was having problems with the Bismuth as well. I’ve never trusted it myself I always go with the lead it always seems to work better to me.
pls school me! First impression makes me think material is being wasted from crushing to pouring the molds. I see this elsewhere but when the 'over pour' into molds obviously too small to hold all of the liquid rock? Do you lose anything? How much carabiner material is included into the crushed powder? Does that matter? Just curious and first impression makes it look curious. Would this waste affect the numbers too? Thanks much! Nice video
I got two bags and when the first one was just his waste and I pulled about .04 gm out of the dirt and dust waste. I am still crushing and I also got a bag of the large samples. With bags are worth the price. Have an idea I am using to crush rock to powder in just minutes. No dust
That was supposed to say crushes. Lol I like how much powder and how fine you get the ore. I find that I am getting more gold from the cleaner white quartz. And I crushed some nice specimens and didn't get any gold. Lots of sulfides
@orophilia I am trying to patent it. If you have any ideas on how to go about it, that would help. Can't find an honest patent company. They may be honest, I'm just nervous throwing 1200 in the wind and hoping it comes back.
I have had strange results with Bismuth also. I think it may have a factor because of its brittleness. and copper in it can take it into the cupel. It is fun doing it but I do find it challenging. One day I was about to give up smelting all together after 40 smelts and no positive result that night I was doing 4 cupels at the same time and God said to look and see what you have and all 4 were positive 2 where quite small and the other two were 2/3 the size of a BB so I press on. It is hard to learn a new trade with being discipled and lets face it all of it is hard work and the acids and temperatures are very dangerous mixing and boiling acids making lava is not a normal pastime for many. Sometime I wonder how I got myself into this not realizing the many dangers but I think the real goal is God refining us.
Great video and explanation! Could the metal from the carabiners be contaminating? Also could your separating specimens be affecting the concentrations in your tests due to the point you had at the end that the concentration is variable/inconsistent?
Since I took the samples from the same batch of ground and mixed ore, I think they should be quite similar. I tried to remove the iron with the HCl, but I'm not a chemist, so maybe. -- Dave
I've commented on J's channel when there were some complaints on the price bs value/gold content and im just like wtf. If J misrepresented anything then ok, but these bags are for hobbyists to do with what they want. Not even the mining compaines are guranteed a profit for any of the work they do, so some critics need some perspective when it comes to expecting the value of the gold one can extract bersus rhe work needed and what they paid for it. That's just reality. But i am very happy to have found an independent channel to show what their reaults were. I get to pretend for a little while that i could do this, lol. If theres anything I can say about your process it's that I'm concerned about the surface area of the iron rods you put into the crucibles, but you obviously know what you're doing so my criticism doesn't mean a whole lot.
This chanel is great..we get to see more of what comes out of jasons mine and they type of recovery the smaller guy with the small equipment does.... This guy turn the ore into baby powder 😊😊
I would dump the bag out and pinpoint metal detect it first. That whining singing sound of AU gets my heart pounding. Then the search is on with Gold Fever. Thanks for showing the chemical process to get to an actual payday.
I wonder if the soft bismuth was from alloying with tellurium. In one of his recent videos he mentioned that he found out the silver sulfides in his ore were tellurium.
I just wondering that flour gold in panning, you crushed those rocks down to a moon dust texture wouldn't it also make the gold do the same? also looks like the gold exploded in the bismuth you could see gold specks on the rim of the crucible.
Yes, the gold was all over the cupel. I'm trying some new experiments to see if I can get better results. The gold particles were very small, so fine crushing is needed to liberate them.
Hi Keith. I have two homemade units. The small one I built for knife making and the larger one is/was for pottery. I use the larger one (4kW) for smelting and the smaller one (2kW) for cupelling. The bricks are the soft ones rated to 2300F. -- Dave
Jason on MBMMLLC has old video of how he built his. Shopvac is blower and propane torch is heat. Fireproof ?wool walls. Thermometer digital beam for over 2,000°F readings.
Hi teacher, I need your help. For the gold test, pulverizing the stone, adding hydrochloric acid, removing the liquid, adding zinc powder, and then tin chloride, is this method correct?
This is well beyound my skill level. It is neat none the less to see . At what amount of gold does it become a worth mining? 5 grams per ton. Its a difficult question to answer im sure. Just me thinking.
@@orophilia thanks for the reply. For me id like to see a much higher amount per ton. Possibly 1/2oz. Per ton and it would be seasonal. I dont want gold fevor. It has ruined many lives. So yes there are many factors. Have you ever dug a ton of materia. I have and its brutal work. Its can be very dangerous too. I spent 40 year in construction so im done with risking my life for a living. Now im a armchair adventurist .i do find the idea of poking around looking for gold. If its not too hard. Im 65 this year and getting older by the day. l
Is it possible that the AR vs assay result difference was from silver that the AR would bypass? The bead looked very gold in coloring. The bathtub type rings in the bismuth cupel is curious. If you don't cupel at the melting point of gold/silver, you won't get a melted bead - Melting point of bismuth (271.5 °C, 520.7 °F) Boiling point (1564 °C, 2847 °F) very odd that happened. If there was an amount of copper in either collector metal, it will pull the gold/silver into the cupel and skew your results. excellent content as usual :) keep up the great work!
Yes, the AR would bypass the Ag, but I don't think there's much Ag in the Au by the look of the bead, which is really beautiful under a microscope. I'm guessing that the panning process misses some, and the AR doesn't get all the Au in the sulfides. I've seen this many times on other ore. I don't see much copper in these samples. I'm thinking about sending some samples to a professional, and I'll keep experimenting. I don't know what's going on with the Bismuth.
@@orophilia From an assayer friend of mine : manganese in the Chapman flux can cause silver to stay in the slag. Chapman flux is not generally for assay.
@@orophilia I think you would have to go the AR route - I believe it dissolves in the solution along with the gold. It can then be dropped out of solution - I don't recall if that is done before or after dropping out the gold. Don't go by the "density" (I think you meant transparency) of the solution. A AR to the ore sample a bit at a time, until you don't get any further bubbling or brown gas. Let it settle for a few minutes, then check a drop of the fairly clear solution with Stannous chloride. If I recall correctly, that is the test specific for gold in AR solutions. Sreetips covers the test in detail in several of his videos.
How do you figure +/- 10% and 30% when your Fire Assay was 100% over your Aqua Regia Measurement? Where did the missing lead and bismuth go? Should you have used a bigger final collector basin to avoid possible escape?
Do you have available plans for your little crusher? I like that a lot! I have bought 2 bags of Jason's muck, have separated the pieces out but looking for a way to crush without buying an expensive crusher that will not get used much. Thanks.
Watching you mess with all that powder... why is Deadpool going through my head? "That's the finest gold I've ever seen.." yeah that happens when you beat the living hell out of it and classify it down to a super small size.. you aren't going to have flakes come out of a fine mill. Realize that the bismuth also likes to stick to the steel rod and takes gold with it.. something Jason has been having a lot of problems with in his smelts. But still that's nowhere near the 3-4oz/t that he's been claiming.
I have never seen such a claim from Jason, although if he high graded that vein, it would probably assay that high - or higher. Someone stated that he has said his mine run veined quarts is producing up to 1 oz/ton. That is not much, seeing all the work that is involved just getting the ore out of the mine.
Hi there, I was watching the grovie gold hunter, with the same martial he only gets.2 grams witch seem not a lot, I think that with your advice he could get more than that,
Greetings from Lithuania ;) I have a note. If we calculate the volume of the gold bead as a sphere 0,4mm, then we get about 0.0335 cubic mm. The theoretical weight of this sphere of pure gold would be 0.0335×19.3=0.647 milligram. Maybe it's worth re-measuring this gold bead with a caliper or micrometer and compare the weight with the theoretically calculated one?
Yes, exactly. I cleaned up the bead in HCl and remeasured it using a digital calipers and I get 0.51 mm, which gives a weight of 1.26 mg if pure gold. The optical measurement works well under the microscope as long as good photos are taken and care is used. Very perceptive, thanks!
I have some magnetite silica gold ore from BC Canada. If you are interested I would gladly send some your way. The gold is visible but the high iron would be a challenge!
11.5g per ton seems low. I swear Jason said in one of his videos that he was getting 1ozt per ton which is 31g. Do you think this was purely due to the nugget effect or could there be other factors in play?
@@orophilia thanks for all your videos. And thanks for the information and knowledge you share with us. I hope you get 1 million subscribes. whats the link or name of the item ?
Hello, it seems to me that you made a mistake in the calculation of the chemical analysis. You're missing the division of the sample under investigation, which you diluted. In the video, it's at 17:40. It should be (5.6 g/mT * 2). Am I right?
Re. Rock your crusher Why not use a chain ? I’d start with let’s say 3/8” chain links (ie. 5 links ) not only will be cheaper but also lasting longer. Anyway I like your style. Cheers….. Yvon.
Love that people are buying his ore!

@@MrDalerex I'd love to hear about your crusher! I'll build one and you get the credit. :-)
@orophilia I am trying to patent it. If you have any ideas on how to go about it, that would help. Can't find an honest patent company. They may be honest, I'm just nervous throwing 1200 in the wind and hoping it comes back.
I have had strange results with Bismuth also. I think it may have a factor because of its brittleness. and copper in it can take it into the cupel. It is fun doing it but I do find it challenging. One day I was about to give up smelting all together after 40 smelts and no positive result that night I was doing 4 cupels at the same time and God said to look and see what you have and all 4 were positive 2 where quite small and the other two were 2/3 the size of a BB so I press on. It is hard to learn a new trade with being discipled and lets face it all of it is hard work and the acids and temperatures are very dangerous mixing and boiling acids making lava is not a normal pastime for many. Sometime I wonder how I got myself into this not realizing the many dangers but I think the real goal is God refining us.
Yes, all we can do is press on.
excelent video, thanks dave
Great video and explanation!
Could the metal from the carabiners be contaminating?
Also could your separating specimens be affecting the concentrations in your tests due to the point you had at the end that the concentration is variable/inconsistent?
Since I took the samples from the same batch of ground and mixed ore, I think they should be quite similar. I tried to remove the iron with the HCl, but I'm not a chemist, so maybe. -- Dave
I've commented on J's channel when there were some complaints on the price bs value/gold content and im just like wtf. If J misrepresented anything then ok, but these bags are for hobbyists to do with what they want. Not even the mining compaines are guranteed a profit for any of the work they do, so some critics need some perspective when it comes to expecting the value of the gold one can extract bersus rhe work needed and what they paid for it. That's just reality.
But i am very happy to have found an independent channel to show what their reaults were. I get to pretend for a little while that i could do this, lol.
If theres anything I can say about your process it's that I'm concerned about the surface area of the iron rods you put into the crucibles, but you obviously know what you're doing so my criticism doesn't mean a whole lot.
I trust Jason completely.
This chanel is great..we get to see more of what comes out of jasons mine and they type of recovery the smaller guy with the small equipment does....
This guy turn the ore into baby powder 😊😊
Great video!
I would dump the bag out and pinpoint metal detect it first. That whining singing sound of AU gets my heart pounding. Then the search is on with Gold Fever. Thanks for showing the chemical process to get to an actual payday.
I wonder if the soft bismuth was from alloying with tellurium. In one of his recent videos he mentioned that he found out the silver sulfides in his ore were tellurium.
New subscriber - great stuff!
سلام. استاد وقتتون بخیر. عالی عالی بود
I just wondering that flour gold in panning, you crushed those rocks down to a moon dust texture wouldn't it also make the gold do the same? also looks like the gold exploded in the bismuth you could see gold specks on the rim of the crucible.
Yes, the gold was all over the cupel. I'm trying some new experiments to see if I can get better results. The gold particles were very small, so fine crushing is needed to liberate them.
@@orophilia If using the assaying process, a fine powder is not needed. See CM Hoke's book - which has a thorough discussion of ore assaying.
If I may ask, what is the furnace you are using?
Hi Keith. I have two homemade units. The small one I built for knife making and the larger one is/was for pottery. I use the larger one (4kW) for smelting and the smaller one (2kW) for cupelling. The bricks are the soft ones rated to 2300F. -- Dave
They look quite professionally done. 220V no doubt. How many amps?
Jason on MBMMLLC has old video of how he built his. Shopvac is blower and propane torch is heat. Fireproof ?wool walls. Thermometer digital beam for over 2,000°F readings.
Thank you. I know Jeff Williams had one also, but it was a top load
Is Jason selling bags of tailings?
I think he sold a bag of concentrates, but I don't remember exactly.
I believe it is all mine run ore - no tailings. But there is bound to be some country rock in the bag.
Hi teacher, I need your help. For the gold test, pulverizing the stone, adding hydrochloric acid, removing the liquid, adding zinc powder, and then tin chloride, is this method correct?
No
THANK YOU
When separating mark both sides before separating.
This is well beyound my skill level. It is neat none the less to see . At what amount of gold does it become a worth mining? 5 grams per ton. Its a difficult question to answer im sure. Just me thinking.
Yeah, depends on many factors. The price of gold being a big one.
@@orophilia thanks for the reply. For me id like to see a much higher amount per ton. Possibly 1/2oz. Per ton and it would be seasonal. I dont want gold fevor. It has ruined many lives. So yes there are many factors. Have you ever dug a ton of materia. I have and its brutal work. Its can be very dangerous too. I spent 40 year in construction so im done with risking my life for a living. Now im a armchair adventurist .i do find the idea of poking around looking for gold. If its not too hard. Im 65 this year and getting older by the day.

almost looked like the bismuth may have wicked up the side of the cupel possibly
Yes.
Is it possible that the AR vs assay result difference was from silver that the AR would bypass? The bead looked very gold in coloring. The bathtub type rings in the bismuth cupel is curious. If you don't cupel at the melting point of gold/silver, you won't get a melted bead - Melting point of bismuth (271.5 °C, 520.7 °F) Boiling point (1564 °C, 2847 °F) very odd that happened. If there was an amount of copper in either collector metal, it will pull the gold/silver into the cupel and skew your results. excellent content as usual :) keep up the great work!
Yes, the AR would bypass the Ag, but I don't think there's much Ag in the Au by the look of the bead, which is really beautiful under a microscope. I'm guessing that the panning process misses some, and the AR doesn't get all the Au in the sulfides. I've seen this many times on other ore. I don't see much copper in these samples. I'm thinking about sending some samples to a professional, and I'll keep experimenting.
I don't know what's going on with the Bismuth.
@@orophilia From an assayer friend of mine : manganese in the Chapman flux can cause silver to stay in the slag. Chapman flux is not generally for assay.
@@AUMINER1 Yes, that's actually good in my case because I don't want Ag in the bead if I can avoid it. I'm only interested in the Au. Thanks!
Wouldn't it be funny, if Jason's gold mine turned out to be richer in Palladium ?
It's a long shot, but yes it would. I'm going to try to figure out how to make some sort of estimate of Palladium. Chemists, please help! -- Dave
@@orophilia I think you would have to go the AR route - I believe it dissolves in the solution along with the gold. It can then be dropped out of solution - I don't recall if that is done before or after dropping out the gold.
Don't go by the "density" (I think you meant transparency) of the solution. A AR to the ore sample a bit at a time, until you don't get any further bubbling or brown gas. Let it settle for a few minutes, then check a drop of the fairly clear solution with Stannous chloride. If I recall correctly, that is the test specific for gold in AR solutions. Sreetips covers the test in detail in several of his videos.
That's a hell of a long sleeved sweater you're wearing! Cashmere? ;-D
tis a paladium mine... extremely valuable 😅
It's a gold mine. Extremely valuable.
How do you figure +/- 10% and 30% when your Fire Assay was 100% over your Aqua Regia Measurement? Where did the missing lead and bismuth go? Should you have used a bigger final collector basin to avoid possible escape?
Perhaps you can watch the next episode.
Do you have available plans for your little crusher? I like that a lot! I have bought 2 bags of Jason's muck, have separated the pieces out but looking for a way to crush without buying an expensive crusher that will not get used much. Thanks.
Here's a link to the video: ruclips.net/video/LnkZ4Ugkyu0/видео.html
@@orophilia I thank you, much appreciated
Watching you mess with all that powder... why is Deadpool going through my head? "That's the finest gold I've ever seen.." yeah that happens when you beat the living hell out of it and classify it down to a super small size.. you aren't going to have flakes come out of a fine mill.
Realize that the bismuth also likes to stick to the steel rod and takes gold with it.. something Jason has been having a lot of problems with in his smelts. But still that's nowhere near the 3-4oz/t that he's been claiming.
Yes, the dust is dangerous, so I always use a respirator.
I have never seen such a claim from Jason, although if he high graded that vein, it would probably assay that high - or higher.
Someone stated that he has said his mine run veined quarts is producing up to 1 oz/ton. That is not much, seeing all the work that is involved just getting the ore out of the mine.
@@buggsy5 Most of what he's doing right now is digging to the rise. Once that is done they will go more for the veins. I think...
I have some ore you can do another video with?
Hi Travis. Yes. Contact me at Orophilia.gold@gmail.com.
Greetings from the BIG SKY of Montana. Palladium seems to be the real question to me. Is it considered a precious metal?
Yes, for sure.
You only used 1/4 of the gold in solution from aqua regia. Don't you need to multiply your results by 4 to get correct concentration?
3 drops X 4 (for dilution) = 12 drops, which is what I used in the calculation.
Thank you, keep working.
Have you tried using motorcycle chain in your grinder? It might last longer and do a better job
That's a very interesting idea! I'll have to think about it.
May want to pull that battery before opening and putting your fingers inside... Just a suggestion
Hi there, I was watching the grovie gold hunter, with the same martial he only gets.2 grams witch seem not a lot, I think that with your advice he could get more than that,
The iron content could be from the carabiners breaking down as you grind it.
Yes, certainly some of that.
Greetings from Lithuania ;)
I have a note. If we calculate the volume of the gold bead as a sphere 0,4mm, then we get about 0.0335 cubic mm.
The theoretical weight of this sphere of pure gold would be 0.0335×19.3=0.647 milligram.
Maybe it's worth re-measuring this gold bead with a caliper or micrometer and compare the weight with the theoretically calculated one?
Yes, exactly. I cleaned up the bead in HCl and remeasured it using a digital calipers and I get 0.51 mm, which gives a weight of 1.26 mg if pure gold. The optical measurement works well under the microscope as long as good photos are taken and care is used. Very perceptive, thanks!
wasnt the reverse true with the last vid? with fire vs chem assay?
I always get more Au from a fire assay as long as I have well mixed and well divided material
Video yang sangat luar biasa❤❤❤
When it comes to chemical processing, watch Sreetips, that's his jam.
Yes, I've watched many of his videos. Here the problem is detecting and measuring milligram amounts of gold.
I have some magnetite silica gold ore from BC Canada. If you are interested I would gladly send some your way.
The gold is visible but the high iron would be a challenge!
I'm interested, but I have other commitments for the next couple of months. Thanks for the offer.
@@orophilia no worries, the ore isn't going anywhere! If you ever have the urge for a new challenge.
Take care,
Is that minable material in a large scale? Appears to me you had more expenses in the extraction alone than the total value if the gold produced??
That would be up to Jason to determine.
If he can sell enough slobs showing visible gold as specimens, the mine might produce a nice income.
11.5g per ton seems low. I swear Jason said in one of his videos that he was getting 1ozt per ton which is 31g. Do you think this was purely due to the nugget effect or could there be other factors in play?
I trust Jason completely, so it could be the nugget effect. I'd do more work on this.
@@orophilia fair enough, its very interesting nonetheless.
Pyramid Type Graphite Moulds wear did u get it from
from Amazon
@@orophilia thanks for all your videos. And thanks for the information and knowledge you share with us. I hope you get 1 million subscribes. whats the link or name of the item ?
@@orophilia sow u have the link for it ?
can you test for tellurium , those deposits are known for it ?
I'm not a chemist. Perhaps we can learn together.
Hey , is an average of 77pm of gold and 2000 ppm of silver ore is feasible for mining ?
In my opinion, yes.
A lot of the gold obtained these days is recovered as a byproduct of mining copper or silver.
2000 ppm (if by weight) is only 2 mg ton.
I love his stuff. I crushed some and got a good amount of gold. I ran it through my clean up sluicebox
Awesome
making maths fun. (kind of)
Hello, it seems to me that you made a mistake in the calculation of the chemical analysis. You're missing the division of the sample under investigation, which you diluted. In the video, it's at 17:40. It should be (5.6 g/mT * 2).
Am I right?
I used three drops of the standard solution to equal one quarter of the sample fluid, so 3*4 = 12 drops.
@@orophilia Oops, I apologize. I overlooked that.
Why don't you just dump the bag on your table top so we can see everything all at once not separated
I'll start the next video that way. Thx.
27:21 I'm 99% sure it was Nickel 🙂
Re. Rock your crusher
Why not use a chain ?
I’d start with let’s say 3/8” chain links (ie. 5 links )
not only will be cheaper but also lasting longer.
Anyway I like your style.
Cheers….. Yvon.
I'd love to use beefy chain, but there was no room in the chamber. I need a much bigger unit. Thanks for the comment. -- Dave
