2017-2-26 The gold anodes are made exclusively from the gold from the silver-cells, which assays about 875 thousandths gold, from 100 to 125 thousandths silver, and a small amount of base metals. This gives, in the first cells, cathodes about 998.7 fine, which, on being re-treated in the second set of cells, produce gold
Silver ions, obtained by this means are collected in high purity (99%) by applying appropriate electrolysis conditions. The interference from other metallic impurities, namely copper, gold, iron and zinc, is eliminated by choosing an appropriate electrolysis potential. Key Words: Silver recovery, silver extraction, thiosulphate leaching
2019-6-10 the case of gold and silver the results were not that efficient either due to the low HCl concentration, which is the case of tests 1 to 8, or higher solid:liquid ratio associated with different reaction time, as pointed out in the tests 9 to 16, even with higher HCl concentration. 146.
2021-5-6 Gold is typically thought of as a metal used for coins and jewelry. However, its resistance to corrosion, conductivity and malleability makes it useful for electronics. When electronics become defective, there are ways to recover the gold, such as reverse
2011-3-18 To extract silver from a silver-plated item, mix a solution of ¾ sulfuric acid and ¼ nitric acid inside a metal pot, heating it up to 176 degrees Fahrenheit. Attach a copper wire to the object you wish to extract silver from and dip it into the solution for a few seconds.
