This is awesome. I have not seen anything on copper extraction. I have seen gold and silver, and copper is usually involved as part of the base metals of those two. But getting the copper out I have never seen. So good for you to show us how it's done.
@@mineoperator I have a question, I would be grateful if you could answer it. How did sulfuric acid dissolve gold and combine with copper? Does sulfuric acid dissolve gold? Thank you.
Holly Cows! This whole inorganic chemistry gave me flash backs to college, then university. Very profitable to have knowledge and skills, the fun begins when you love to apply them and create a reality. Access to the required tools sure helps.
If you use a perforated plastic bucket with the coarse ore in it, that fits in the leach beaker you can strain the fines off to the bottom and keep the bigger pieces clean. It also helps circulating the leach by simply lifting the leach bucket up. An aquarium air bubbler underneath helps speed dissolution up. Keep the lid on for tiny drops flying out.
It's probably worth thinking about a production scale leach plant. Also remember that electrowinning allows you to recover the acid as well as the copper so you can reuse the acid several times. As ever crushing the rock and sorting it for the blue bits (!) minimises the acid used and lost and keeps the acid solution as copper loaded as possible to maintain good yields at available currents. Given your location solar power would probably feed a great electrowinning setup with no power bill, or diesel costs.
Great points Seymour Pro. A parallel vein in the hanging wall is 2' thick and has chemically assayed at 2.5% Cu. We'll take your advice and look into a production scale Leach plant with electrowinning. If you have other ideas, feel free to reach out to us.
Yes, I would like to try a small 30-50 lb batch test recirculating electrowinning cell and see how long I can reuse the leach before needing to filter with activated carbon or resin. The commercial mines heap leach.
Make sure you test your acid consumption first. If there are a lot of carbonates in the gangue material, acid can end up being a considerable cost (+ disposal of gypsum tailings).
For your size of operation, stockpile it, enrich it with shaker table and if you can afford it a flotation plant and sell it as bulk to a smelter. Leach and EW plants are hard to get right, dangerous and generally very expensive.

OMG. I don't know how much more of this I can take this evening. I just watched SilverStroll video and you have a clock that runs backwards... L0L. Oh My, Priceless !!!!
Excellent video! The latest theory is there was mining all over the Giza plateau and the pyramids were used to make the sulfuric acid and other chemicals. To think this was going on pre 2500bc is amazing.
That was badass. Thanks for telling us your clock goes backyard. I was really questioning the process when saw clock going backwards. Excellent refinement
I‘ve handled things within boxes according to specific instructions based on stringent requirements and I have done so whilst using external cameras too. It is a bloody nuisance to get the exposure right and damned I was to record even the procedure followed to bring the camera to the machine itself. Yes, card was full at some time too 😩 It is a nuisance to narrative and follow written instructions and keep an eye on the camera but doing it with H2SO4 in any concentration isn’t fun but necessary. Commend you doing this as safe as possible (got H2O2 droplets launched at me once, since then I‘m obsessive with eye protection) and the beautiful colours recorded. Well done.
An Epiphany. Be this the initial recovery of Cu for your company, run this procedure again 3xs the load, to recover a goodly chunk of Cu. Find someone crafty, goldsmith or indigenous craftsman, along with your ability to smelt metal, to fashion a functional yet crude looking, arrowhead AND spearhead. You could use the Spearhead as your company logo and give a summary of its creation in your channel and website as an intro.
Sorry to hear about the burn. Yeah, we do our best to be safe when using acids. We're looking for different reagents for leaching copper. Preferably cost-effective reagents.
Love the video !!! Question though.... after the xrf, the sample showed three9 copper and a .07+- Au. Can that amount of gold alone make that copper such a brassy color ? Although perhaps the color is skewed by the camera and the sample may not be as "brassy" as it looks.
I believe the discoloration or brassy color on the copper is from the melting/cooling process, oxidation, impurities and flux. If I pickled in dilute sulphuric acid 5%, the borax and other impurities will come off leaving a bright copper shine.
For my ability if I were to reuse the Copper Sulphate, I would need to use electrowining to remove the copper out of the solution. Balance the Sulphuric acid to water ratio to 5% and its good for another leach.
After Dissolved the copper in sulfric acid, which one acid is used for seperate copper powder from this copper solution. ?? such as (mcbs) solution is used for gold powder to separate from aqua regia. . i hope you understand my question. mean which chemical or acid is used for copper separate from copper solution. . except steel or iron . . . ❤❤❤❤❤❤
The only three ways I am able to get copper out of copper (II) Sulphate is adding iron, electrowinning and activate carbon filtration. I don't know of another acid or liquid to drop the copper from copper (II) sulphate.
Okay, now that was #€*¥in cool!!!!! Yes I want the other reaction. I think everyone does that geeks out on this science stuff. You have no idea how much this video speaks to me. Thank you
@@mineoperator wishing for a love button. I have so much respect for you not making that a dumbed down video for the masses but instead explained it scientifically for those who can follow the bouncing ball. Good on you!!! Heck yeah!!!
as you mention, I think the 1 liter liquid solution may have been enough for 1 pound of sample. I am very grateful for the excellent work, I had never seen how metallic copper is obtained from copper rock.
The ratio is 5% sulphuric acid. The volume of water needed for a ton, I dont know. I will need to find out what the saturation point is for Copper at 5% sulphuric acid. Only way I know how to measure is specific gravity.
I would grind it to -500 mesh and work it in a stirring slurry tank to ensure 100% extraction. Otherwise, you're leaving too much metal in the gangue. Once it has been stirred 48 hours as a slurry, then let it settle 48 hours, and siphon off the solution to reduce the necessity for trying to mass filter it.
Thanks for the suggestion! Do you think you'd create slimes that would need to be filtered out with a grind so fine? -500 mesh is extremely fine and wouldn't be possible to scale up, unless we buy a ball mill. But slimes/silts would have to be addressed.
Going from 1/8- to 500- is a little extreme. You want to be able to transfer your test method into production... considering cost and what will actually work. I would suggest getting material to mostly 80- ..and see if there's any difference in recovery .
@@mineoperator Personally, I would use mass salt flotation if the mineral content seems rich enough, otherwise, I would use a vat leach and decantation to get the process going. For the cost, while salts can readily float away a lot of gangue with no potential loss of the costly salts [assuming you know to filter the float], if the minerals are hard to get to by flotation, one can simply use an ammonia leach to take away the ligands of the desired minerals, and leave the less desired materials. A warm ammonia solution is no less dangerous than a cyanide solution, but easier to obtain, and works in a way which produces fewer long term hazardous byproducts.
Since crushing is the most expensive part of mineral processing, we would have to perform some bench scale testing to determine how little crushing can be performed to recover the most copper. If you can recover 85-90% from a coarse crush for heap leaching, would it be worth it in CAPEX to install the equipment, power requirements, ultra-fines handling, filtering, to grind down 100% to 200 mesh to recover the remaining 10%. It's definitely worth the work to find out. If the CAPEX you can afford will only accommodate a coarse crush, you'll be stuck at 85-90% recover until you can afford the upgrades.
Does sulfuric acid effectively react with sulfide ores? I thought that sulfide ores must be roasted first in order for the sulfuric acid to do it's trick. Please enlighten me with your experience and knowledge and apologies for bothering you. Im just a bit too invested in this stuff mentally, it so satisfying and entertaining XD
@savvy.dispatch Great question. Unfortunately, not. If you're looking to oxidize copper sulfide ores such as chalcopyrite, bornite, covellite, or chalcocite, an alkaline solution will prevent passivation. Acidic lixiviants will be consumed rapidly and require more maintenance. Roasting is an option for small-scale applications that I am aware of. I have a technical report on alkaline lixiviants. I'll review it again and provide further guidance. I need a refresher on this topic.
@@mineoperatorI have made key ring holders out of Cu bus bar pieces 3 x 1 x 3/8. Can put a logo and dimple, then buff, polish. You'll know you got your keys by the weight.
I just want to know how you can see your aqua blue beta in the blue water. I would think that dying your aquarium water blue distracts from the fish. Enjoying your videos keep them coming.
Great question. I'm still doing some research to give you a good answer. I believe some sodium or potassium salts, along with other base metals that went into dissolution but didn't drop out with iron, such as zinc or manganese. Still doing some research on that one.
Actually the chrysacholla is worth more as jewelry grade stone than it is to process it? All the specimen stuff is high dollar. Get a tile saw and start cutting it for patterns you like. Of course the more gemmy the better.
The stone that was not able to be slabbed and cut into cabs was used. It was way to fractured from our initial extraction method. We have all the stable AAA chrysocolla.
Try a similar experiment with white vinegar and electrolytes.. cabon from new d batteries and. Stainless steel plates. Electrolytes is the only way to get pure copper. The vinegar works but my memory is flipping on the type of vinegar...might not matter.

Very interesting experiment! What you said at the end of the video makes it sound like you guys won't go after xopper comercially. I understand if its not viable, but I would be interested to see more copper, next to the gold or course! 😅 The process with acids shown here probably isn't financially profitable. I'd imagine smelting would be a way to process such ore on large scale? 🤔
We want to try a few different reagents and recovery methods such as electrowinning. Dezo, Potassium Iodide, and Eco-Goldex O series might be much cheaper. Who knows, maybe we'll get a large exploration company interested in our project.
Nice vid, we work the same area, I use hydrochloric acid and ammonia method outside in large container with aeration added and let the sun provide my heat. Takes longer but found it cheaper. I’m Ronnie , Ron has my number if you want specific details.
Just some food for thought, people are literally dieing, steeling cooper. Have you thought of selling the ore? I guarantee you someone will be willing to leach the copper and what ever other valuable minerals are there, out of the ore for resale.
Hey Shaggy Dude. Awesome name btw. We have thought about that. One retired mining friend told me to get proficient at getting the ore out of the ground. You don't have to know how to do it all. There will always be buyers for ore. We need to look into who to sell this ore too.
Maybe try to produce a copper product like wire or something and the copper would be worth more..in theory. I think you would yield more copper if ground finer and you added the little stir spiner in first step.
