Electrolysis Refining Silver

Apr 24, 2021

The result of this processing is 999.9/1000 fine silver. Silver electrolytic refining allows refining a minimum of 25 kg/cycle in fine bath and with 980/1000 fine silver anode. The system consists of an AISI304/316 steel frame, one or more self-extinguishing PPs tanks with support structures for anodes and cathodes, suction points, stairs and

    Upon electrolytic refining of the copper, insoluble impurities, called slimes, gradually accumulate at the bottom of the refining tank. These contain the silver originally present in the concentrate but at a much higher concentration; for example, a silver content of 0.2 percent in the sulfide concentrate can result in a slime containing 20

This can exist in the form of an old silver necklace you have lying around or an old computer part from your outdated laptop.

    Feb 03, 2008 September 10, 2008. A. Assuming your scrap is either .925 or sterling there isn't much need to really refine it and it's impossible to refine to purity without a electrolysis. The purity of anything marked 925 or Sterling is already 92.5% pure silver. One method of reducing some of the impurities would be to dissolve the silver in a 30-35% nitric acid solution
