Really interesting to watch this recovery process! After you had ground up the IC chips in the ball grinder, I was thinking "oh, why not just dissolve all that iron with HCL (or maybe copper chloride?)" - but you answered that question right away: I guess it would take quite a lot of acid to do that! Very nice video! 👍
I’ve seen between .5g and 1g per 1kg for yields from that type of chip, so I’d say your recovery was awesome. I’m impressed with your board recovery as well👌🏼👌🏼
@@Reasonist thanks Reasonist, I don’t know if the result is good or bad, first time ever paying any real attention to DDR1. I’m happy with it as a basis to look at going forward, and now I know what the minimum I should be looking at these boards for future value
Hi Charles, thanks for watching. I explained to another user that I have no idea what the yield should be for these chips specifically, normally I just dump RAM IC's in with other stuff that needs the same process. What comes out is what comes out. From watching other you tube video's the results vary for these chips. I do keep all my wastes in labelled containers so the filters and remains are still there. I might give it a go and see if I missed much but will have to wait a while, got a few other things on the go at the minute. p.s. Have you any idea what the going rate per kilo is for these types of IC's? Thanks
@@scouseurbanminer5106 knowledgeable fella recommended soaking the magnetics in a brine solution to convert to oxides ( rust) , the resulting oxides can be rinsed away with hcl!
You have a pretty good process for a minimal investment. Using the “poor man’s Aqua Regia” is definitely a money saver over using nitric. Was making “poor man’s nitric” an option? Using that on the first step could save you time eating the base metals (legs, copper, solder etc) vs the AP method. Overall, awesome job, awesome notes, awesome video. 👍
Wow! :) thanks for watching and the comment... Appreciate it mate, thanks I try different things each time I run batches to see what works best for me. I don't record every batch I do, only if I have the time to put it all together with recording weights etc throughout. It doesn't look like it but putting a video together that long with all the details takes way longer than the actual process. I've got better at it but it still took a few months overall as I live in the UK and all my stuff happens outside so its delayed by weather more often than not. In my other "how much" video I used poor mans nitric for the fingers as the first step based on Geo's poor mans nitric video ( ruclips.net/user/results?search_query=geo+poor+mans+nitric ). I also use it to disolve the base metals and destroy some carbon after milling the chips. It works way faster but requires a fair amount of hot sulphuric acid. I wasn't keen on messing round with hot sulphuric in such volume and since AP works and is way cheaper for the first step I chose that option for this video. I do try to keep the overall costs as low as possible, not because I am in for profit, more to show that it can be done on a tight budget with a bit of research and time. I would say that part of my goals are to either adapt other designs or come up with similar alternatives to established methods without spending a fortune. I am always open to idea's to improve or different things to try and I think I have watched every YT video on the subject. I have also read thousands of hours worth of content on the gold refining forum always looking for ideas to incorporate. At the minute I have been playing around with melting/casting aluminium for a project so haven't looked at more refining for the last few months. I will try to get the next "how much" video out at some point. The recovery stage is pretty much done, just cant get outside as it rains/snows/hails all the time. Thanks again NE :)
Excellent work. Thank you for the sweet video.!!. Quick question, did you get close to your expected yield? I hate bringing it up because you did such an awesome job, but I believe you should have incinerated the chips again to a white powder after you washed/gravity separated them. Carbon is a thief and does not want to give up the Gold.. :) Again, Great Job.
@@tntmadness3138 thanks for watching tnt, I have no idea what the expected yield is from these. I expect that my result will be on the low end and there is some more to get so I never throw the wastes away. I save them all up labelled separately just in case. The video is more an example of what you should realistically expect. I figure if I can get that with my setup as it is then that’s a fair estimate, without spending thousands for equipment and running loads of batches to get your experience level up. I’ve read many times about a second incineration after pyrolysing the chips initially but I just went with the majority of the chips turned to fine powder just squeezing them with my fingers so I don’t know how much more burnt they could get. I agree a second incineration after milling may pay off with a higher yield but the only way I can think of for testing to check the voracity of it would be to do an even split of a large batch, by even I mean literally cutting the ram sticks in half and separating out the chips to see if there is a difference between identical batches and then refining them with lab level techniques. Could make for a good video to be fair, I might consider it for future content. In any case as I have the filtered remains I know I haven’t lost much and if there’s any there I will get it at some point, hopefully you’re right and there’s a few grams hidden away for the future. Time will tell on that. My old process used poor man’s nitric leaches to remove base metals and a side benefit of that would be the sulphuric acid would destroy the carbon similar to a wet ashing method preventing it from stealing the gold. I would have gone with that again but I’m out of sulphuric and getting it in the UK has become more difficult. I am working on a method where there is no need to burn the chips at all but rather grind them to fine powdered plastic then simply remove the plastic by sluicing. it will be a long time in the making as I have way too much stuff to get rid of first. My next video is already underway and I expect will take at least a couple of months. Thanks again for your your kind words

I would say you are low on the yield. You should be getting close to 1g per kg of ram but it does depend on what type of ram you are dealing with. The lowest i have had is about 0.75g/kg and highest is 2g/kg
Thanks for watching Walkthrough. I agree there may be a little more to get, in fact the temp stockpot definately has a thin layer settled out but it's taken over two weeks and doesn't look like a lot. A 4th and 5th extraction might get me another small bead but I don't think it would be any more than that and would require a lot more work and acid's. It is what it is on this occasion I'm afraid. I hope you're right and there is some trapped in the remains. I keep them all separate so can always re-visit to see if I missed anything. I already spent a long time putting the video together and its runtime is way more than I wanted. I was hoping to fit it all in 15 minutes as most people wont watch anymore than that. I would welcome some suggestions on what I could have done to increase the yield. Thanks again.
@@scouseurbanminer5106 gold can get trapped in carbon i.e activated carbon maybe try a pirahna solution if you are that brave but be warned it is very unforgiving and only do that if you are confident. But that said for the small amount of gold you are missing it might not be worth it.

I did a similar thing though with fewer RAMs. It seems the gold from the big RAMs is smaller. The small RAMs from laptop have more gold and the gold from their fingers though looking smaller is actually heavier than that of the big RAMs.
Hi Saddiq, thanks for watching and commenting. Didnt know laptop ram are better than desktop, you would think desktop fingers would be better just based on size but appears you have experience wiith that and they are better. I haven't tried laptop ram yet, I have just been breaking them up and putting them in with other things. I should have saved them up. I will save 10kg and have a go with them in the future.
@@scouseurbanminer5106 Yes indeed. If you have the DDR RAM for example just compare the one from desktop and laptop, you will see that some desktop RAMS have only 8 ICs. Some of them don't even have an IC on their opposite side. The Laptop RAMs on the other hand have a minimum of 8 ICs with some even having up to 32 ICs. The maximum number of ICs on Desktop RAMs is 16. As for the fingers, the ones from laptop thou looking small, are heavier for sure.
@@quinton3997 Hi Quinton, thanks for watching. copper chloride I and II is what you end up with when you dissolve copper in hydrochloric acid (HCL) with air bubbled through it or an oxidising reagent such as hydrogen peroxide is added. It is the copper chloride that leaches the copper off the boards to free the gold foils, not the HCL. It will also leach the copper and some other base metals out of the legs on IC chips. Copper chloride is often called AP solution because it generally starts out as HCL + Hydrogen peroxide. The acronym AP comes from Acid Peroxide.
yeah copper chloride wont touch the gold unless you add an excess of hydrogen peroxide. In a way I am using acid so it's not a saving in the beginning but once you have a decent supply of copper chloride you don't need to use as much acid. I have approx 25 litres of copper chloride so I don't have to use fresh HCL every time. You do need HCL at the start to begin the process of making the copper chloride (Although there are probably other ways of making it without HCL but would need to be looked into). You can start a batch of copper chloride with a few litres of HCL and a very small amount of hydrogen peroxide to kick start the reaction (say 50ml @ 3% in 5 litres of HCL) but all you really need is HCL, an air bubbler (Aquarium pump) and time, and copper of course. Hope this helps.
Wait, what? You got roughly 6 g of gold from 10 kg of gold fingered ram memory. You could have sold it to board sort and gotten 6.8 g worth of cash and not worried about losing any money to premiums. Or all that time and chemicals I hope your yield was low and you find more gold somewhere
@@TylerDavis-qb8wd hi Tyler, thanks for watching. Yeah you are correct, I could also have sold it on EBAY for way more than Boardsort would offer. I live in UK and we don’t have boardsort here but we do have other similar companies. I do this as a hobby, I’m not in it for profit but obviously I would like to make money from it but that’s not my intent. I hope you’re right and there is more to get hidden in the wastes. The video was worth doing just to help grow the channel. Thanks again
Hello man, first, you have my SUB #576. I like your analytical approach. I see, you do this on larger scale than me, so what works for me, may not be viable for you. For fingers I use HCl and a bit o hydrogen peroxide (30%), bubler, when solution turns brown (Cu2+), I add peroxide, solution turns green (Cu+) and repeat... When solution stays green, all copper disolved (takes like one week). Cleaning boards, filter, get gold on filter. Then I cupel it with bismuth. Recupel if needed, XRF showed 99,8 % purity, no chemical purification needed. I saw you have elecric furnace, may be you could try this ancient method. Regarding chips, I cut it out, so no legs with solder (small scale), I burn it, crush, HDD magnet in plastic cup extracts iron, sieve out larger metalic parts and sillica (100 mesh), goldwash powdwr carefully, and cupel. May be I loose in gold washing, but no chemicals needed, no chemical waiste to deal with. As I said, what works in small scale, might not work in large scale and vice versa. May be, you can try cupelation, works realy well...
Hi Fran, thanks for watching and sub :) For the leaching of boards and fingers I already have approx 20 litres of copper chloride so no need for peroxide. When my solution starts to get very dark just add a little more HCl bubble air through it and its like new. 20 litres should last me a few years. Peroxide and HCl can dissolve gold. Only use peroxide to get your reaction started when using fresh HCl, and only a very very small amount depending on the amount of HCl. Keep your 30% peroxide in its storage bottle but make a smaller bottle of 3% strength. The 30% is too strong for leaching, you only need a capfull of 3% in 5 litres to kick start your reaction. Once copper starts going into solution it is the copper chloride that leaches the base metals, not the peroxide, although the peroxide will make the reaction faster. Peroxide has the same effect in HCl as nitric acid, its an oxidiser. It takes longer to dissolve the base metals without peroxide but if the peroxide concentration is high enough it will dissolve some of your gold. Not a problem if you have excess copper/base metals as the gold will cement out on the them, but what you don't want is the gold cementing out on the copper traces inside the finger board where you cant get at it, or even worse you exhaust the copper on the boards and there's still active peroxide, without base metals to cement the gold the solution will start to attack your gold. I'm definitely going to look into cupellation, thanks for the reminder. I need to start doing processes that use less acid's. My electric furnace can only reach 1200 but I figure that should be hot enough to melt the gold alloy. I haven't ran it to full power yet. I only really use it for depopulating boards, so I set it to 400C. To be honest I'm scared of it hahaha Sounds like you're doing the right thing with cupellation, keep it up. When you are ready to do your next cupellation record it and post a few video's to get a channel going. There are lots of us on here that will watch them, and I'm intrigued by the process you describe. I have subscribed and will be looking out for it :) We need more people posting content as it breeds idea's and helps build the community. If you're not already a member join the gold refining forum. There's loads of people on there experienced in all manner of refining all types of precious metals. There's a lot to go through but if you are ever stuck someone is on hand to help you out.
@@scouseurbanminer5106 For cupeling is 1000 C enough, some go with 900-950 C, bismuth alloy needs less to get liquid... high temperature keeps oxids liquid and be absorbed by cupel.

Hi TJ, thanks for the info, what do you reckon is the best way to get rid of the ash? I've tried sluicing and blue bowl in the past. BB tends to let you see whats going on so I like that method. I would like to nitric the legs and include it but there's a lot of them and would cost a lot for the nitric here in the UK, probably more than what I expect would be trapped. I was planning on leaving them in the wastes to disappear over time and get any gold back later when doing clean ups.
@@scouseurbanminer5106 do not worry about getting rid of the ash. Nitric it all to strip base metals then AR it all. Yes looks terrible, and a few re refines.... As for the nitric. There are several tut vids here on the YT to make your own from cheaper chems.... Just ideas.
@@tj8244 thanks, my issue is regulations, EU rules forbid possession of nitric above 3%, I’d need 20 litres to do them metallic bits in haha I will do away with the washing step next time to see if any improvement but I still have all the remains sitting at the bottom of a large barrel. Nothing gets thrown away before treatment and they are isolated in their own container so hopefully if there’s anything in there its recoverable, thanks again.
Hi Tri, i'd be guessing at mid-high 90's, gorgeous colour and no visible evidence of contamination, prob 95% would be reasonable estimate, i don't have an xrf to test them. A third refine with ferrous sulphate to drop the gold would probably push them to 98-99%. If I get a chance I will take them to the jewellers and get an xrf done to check

Wait, what? You got roughly 6 g of gold from 10 kg of gold fingered ram memory. You could have sold it to board sort and gotten 6.8 g worth of cash and not worried about losing any money to premiums. Or all that time and chemicals I hope your yield was low and you find more gold somewhere
@@TylerDavis-qb8wd hi Tyler, thanks for watching. Yeah you are correct, I could also have sold it on EBAY for way more than Boardsort would offer. I live in UK and we don’t have boardsort here but we do have other similar companies. I do this as a hobby, I’m not in it for profit but obviously I would like to make money from it but that’s not my intent. I hope you’re right and there is more to get hidden in the wastes. The video was worth doing just to help grow the channel. Thanks again
Hello man, first, you have my SUB #576. I like your analytical approach. I see, you do this on larger scale than me, so what works for me, may not be viable for you. For fingers I use HCl and a bit o hydrogen peroxide (30%), bubler, when solution turns brown (Cu2+), I add peroxide, solution turns green (Cu+) and repeat... When solution stays green, all copper disolved (takes like one week). Cleaning boards, filter, get gold on filter. Then I cupel it with bismuth. Recupel if needed, XRF showed 99,8 % purity, no chemical purification needed. I saw you have elecric furnace, may be you could try this ancient method. Regarding chips, I cut it out, so no legs with solder (small scale), I burn it, crush, HDD magnet in plastic cup extracts iron, sieve out larger metalic parts and sillica (100 mesh), goldwash powdwr carefully, and cupel. May be I loose in gold washing, but no chemicals needed, no chemical waiste to deal with. As I said, what works in small scale, might not work in large scale and vice versa. May be, you can try cupelation, works realy well...
Hi Fran, thanks for watching and sub :)
For the leaching of boards and fingers I already have approx 20 litres of copper chloride so no need for peroxide. When my solution starts to get very dark just add a little more HCl bubble air through it and its like new. 20 litres should last me a few years.
Peroxide and HCl can dissolve gold. Only use peroxide to get your reaction started when using fresh HCl, and only a very very small amount depending on the amount of HCl. Keep your 30% peroxide in its storage bottle but make a smaller bottle of 3% strength. The 30% is too strong for leaching, you only need a capfull of 3% in 5 litres to kick start your reaction. Once copper starts going into solution it is the copper chloride that leaches the base metals, not the peroxide, although the peroxide will make the reaction faster. Peroxide has the same effect in HCl as nitric acid, its an oxidiser. It takes longer to dissolve the base metals without peroxide but if the peroxide concentration is high enough it will dissolve some of your gold. Not a problem if you have excess copper/base metals as the gold will cement out on the them, but what you don't want is the gold cementing out on the copper traces inside the finger board where you cant get at it, or even worse you exhaust the copper on the boards and there's still active peroxide, without base metals to cement the gold the solution will start to attack your gold.
I'm definitely going to look into cupellation, thanks for the reminder. I need to start doing processes that use less acid's. My electric furnace can only reach 1200 but I figure that should be hot enough to melt the gold alloy. I haven't ran it to full power yet. I only really use it for depopulating boards, so I set it to 400C. To be honest I'm scared of it hahaha Sounds like you're doing the right thing with cupellation, keep it up. When you are ready to do your next cupellation record it and post a few video's to get a channel going. There are lots of us on here that will watch them, and I'm intrigued by the process you describe. I have subscribed and will be looking out for it :) We need more people posting content as it breeds idea's and helps build the community.
If you're not already a member join the gold refining forum. There's loads of people on there experienced in all manner of refining all types of precious metals. There's a lot to go through but if you are ever stuck someone is on hand to help you out.
@@scouseurbanminer5106 For cupeling is 1000 C enough, some go with 900-950 C, bismuth alloy needs less to get liquid... high temperature keeps oxids liquid and be absorbed by cupel. I dont use lead, dont like poisonous metals and lead can contain silver, you dont want that in gold. I have pure lead for fire assay, but didnt use it yet... bismuth work nice and is safer. 1 kg of bismuth costs like 40 pounds on aliexpress...

@@frantiseklaluch6605 excellent, furnace should be good enough, looks like I'm going to have to do some homework and give it a few test tries and hopefully not set fire to the small shed that the furnace is in, thanks Fran
lost gold washing away the dust and ash. Fine Gold tends to stick in that. Nitric the legs you threw away also.
Hi TJ, thanks for the info, what do you reckon is the best way to get rid of the ash? I've tried sluicing and blue bowl in the past. BB tends to let you see whats going on so I like that method. I would like to nitric the legs and include it but there's a lot of them and would cost a lot for the nitric here in the UK, probably more than what I expect would be trapped. I was planning on leaving them in the wastes to disappear over time and get any gold back later when doing clean ups.
@@scouseurbanminer5106 do not worry about getting rid of the ash. Nitric it all to strip base metals then AR it all. Yes looks terrible, and a few re refines.... As for the nitric. There are several tut vids here on the YT to make your own from cheaper chems.... Just ideas.
@@tj8244 thanks, my issue is regulations, EU rules forbid possession of nitric above 3%, I’d need 20 litres to do them metallic bits in haha I will do away with the washing step next time to see if any improvement but I still have all the remains sitting at the bottom of a large barrel. Nothing gets thrown away before treatment and they are isolated in their own container so hopefully if there’s anything in there its recoverable, thanks again.
@@scouseurbanminer5106 ouch. Rough regs. Sry to hear that.. And thanks for the vid. I always love to see other people's process
@@tj8244 yeah we’ll manage somehow haha thanks
How pure are the gold beads?
Hi Tri, i'd be guessing at mid-high 90's, gorgeous colour and no visible evidence of contamination, prob 95% would be reasonable estimate, i don't have an xrf to test them. A third refine with ferrous sulphate to drop the gold would probably push them to 98-99%. If I get a chance I will take them to the jewellers and get an xrf done to check
Why copper chloride
Hi again Quinton, I replied in the other comment but YT studio isnt great when displaying messages so not sure if the other comment was an edit of your first comment or an additional comment. Thanks again for watching and commenting.
HOW MUCH GOLD IN 100 KG OF CPU COMPUTER AVG .. CAN U MAKE A VIDEO OF THAT
@@palazzo5875 I’d love too but unfortunately I don’t have 100kg of CPU’s
@@scouseurbanminer5106 HI thanks for replay i dont mean 100kg exact its just number lets say 1kg or 1 lb or ur knowlege with numbers how much can u get in return with pure gold from cpu thanks
@@palazzo5875 ah I see, I have no idea mate but CPUs vary massively, I could do a video when I’ve saved a stack of them up but it would be a while in the making, I have a couple of other projects on the go already
great video but music very loud and annoying.
@@AT-os6nb Thanks AT, sorry if it annoyed you. Do you think it would be better if I lowered the volume down to barely audible and read the text out as narration over it?
Turn the volume down...simple.
yes Drop kusic
Do you live in the usa? If so i would like to ask you to refine some gold for me if possible. It is only about 6 grams but i tried to do the cupell method on it and used bismuth... ended up fully mixing the gold with bismuth and cannot get it back out... So if you want to help me out i would be down!
Hi Gold Fever, sorry I live in Liverpool, UK. Shame cos I would like to save that gold for you. If you have an account on the Gold Refining Forum you will be able to find a local refiner who can help you out.
@@scouseurbanminer5106 Thanks for the info man!
I'm in Winchester, VA . Been refining computer scrap for over 20 years.

Hi just watched your very interesting video.
With a name like scouse urban I suspect you live in the UK 🇬🇧 if so can you tell me where I can buy Nitric acid ?
@@Frenki-gy9zd hi Frenki, thanks for watching. You can’t buy it without an EPP license. I haven’t found anywhere that will sell me it without one. APC Pure will sell it and ship it to a home address if you have a home office license but it is expensive.
How much were all that stuff off ebay did u even make a profit like
@@David-eb2di Hi David, thanks for your question. I honestly don't know the exact cost on this lot. Unlike my previous video I didn't buy all the RAM used in this video specifically to see if it was profitable. I'd say at least 50% came from scrapping out old PC's which I got for free or very cheap. Other boards came from places like facebook marketplace and gumtree as part of scrap computer parts listings.
