    I don't think you need to crush those things at all. There was a lot of silver blowing around in the wind. If you just melt them as they are, you should see the same segregation in your melt that you saw here - carbon floating on top. Putting charcoal (carbon) on top of melts is an ancient method of working metals. It acts as an oxygen barrier because it floats and reacts with the oxygen, forming CO2 "insulation" as the melt is completed. You should be able to do 99% of the job without any fluxes or admixture.

    I'm guessing those brushes are primarily silver-tungsten alloy, from past experience. You can separate the silver using the method you set out with in the beginning, but you need a strongly alkaline oxidizing flux (a lot of sodium nitrate and lye). Under the conditions the tungsten oxidizes and dissolves into the slag, and your silver separates out nicely. Should be a pretty clean lead-free method for those brushes

    your gonna make a fortune!!! i was thinking of doing this for a few years now. I have a few large graphite blocks i got from ebay. They have a copper colored tinge to them so i know they are the brush type graphite for use in motors. I just never knew the silver content was so high! Regular graphite blocks are just dull black. Also don't forget the copper commutators on large motors and generators have a high percentage of silver as well !!!

  • @2010invent

    The carbon will keep much of the silver with in the microscopic form within the carbon it self. Grind all the brushes super fine, burn all the powder to a white ash "very important for it to be white ash" than smelt it all with some borax. you will get all your silver.

    Silver is too expensive for this method and not for the one that involves dissolving it in nitric acid. It is good, however, that you show this method in the sense that it gives good knowledge in general for the passionate man.
    But, for those who master chemistry quite well and do not set their hair on fire and are not suckers enough to work without protective gloves and a protective visor, I remind them that the method of dissolving in nitric acid followed by precipitation with copper gives surprising results in terms of the final purity of the silver obtained.
    If the method of attack with nitric acid is preferred, the metal losses are the lowest, considering its price. The silver passes completely into the solution (colorless) while the graphite remains on the bottom of the container. After relative decantation, the solution is passed to another container through the filter paper in a funnel, after which it is ready to be treated with simple metallic copper. Silver has a lower deposition potential than copper. The silver is deposited on the copper wire / bar, in the form of a black powder, which is very chemically pure. Copper gradually passes into solution, replacing silver, the solution becoming more and more blue. The black silver powder is collected, washed with distilled or rain water, and passed to the crucible for melting, along with a little borax. The result is silver in an advanced state of purity. In this way you get rid of Bismuth and Lead which are two horrors for human health and not only for humans but also for animals.
    Be very careful where you hand over the remaining waste, do not throw it anywhere in nature or in the trash, because if you have a clear conscience, you will not sleep well at night due to possible consequences. : D
    An additional clarification: For good efficiency and speed of dissolution, the first condition is that the motor brushes must be ground very well, until the powder state, and during the reaction with the acid, it must be spun with a glass rod or polyethylene. The container must be made of glass. Nitric acid is extremely corrosive, so do not play with utensils made of anything other than glass, preferably laboratory.
    For what I chopped here, I insist on a digital beer in a silver mug ! ;)

    When I worked in a Gold Assay lab they had large furnaces cooking lead 24/7. The lead fumes and particles were handled completely by Electrostatic Precipitators and a Bag House.
    That sounds complex but it's not as bad as you think. I'm sure a Welding Fume Collector with filtration could be employed near the source. Since you have welding eqpt it might be worthwhile.

    I think the chemical way is a muche cleaner way. It's with almost certainty environmentally cleaner and from a financial point of view more profitable in the long run.
    Because you get a muche more pure result in the end.
    Offcaus it all depent on what you are planning to do with it. But it's interesting waching someone taking a different approach.
    I recommend taking a look at Sreetips to see it done the other way.

Unless you are doing it as a hobby where it really doesn't matter. In this case, the 90 grams of silver would be around $70. On the surface the ROI seems very low to a loss. I realize that quantity plays a big role too.

Had lots of that brush material that ended up being recycled with copper graphite scrap bought lots of it to make brushes for tools alternators and starters. Was pleasantly surprized when i found out the silvery ones literally were silver graphite composite. You can put a chunk of this material in an electromagnetic pulsed coin crusher and make small diamonds in a silver matrix. Good times.

    Hi Jase, any chance you could do a video upscaling the size of your sulphide / black sand con smelts but still within the resources of a professional miner ... we’re getting about 5 tonne/week .
    I caught part of one of your melts using a large crucible and small overhead crane (2 people ) but can,t find it again ?
    I think a lot of the operators would benefit from your insight and keep up the great ideas they are really inspirational

    How would you suggest extracting the silver out of 40% silver clad coins? I would love to see that video.

    So why did you not use zinc for your collector metal and then copel the leftover zinc mix?

    Can you do a comparison between bismuth and copper powder as the collector metal? ....and then removing each collector metal?
