Cyanide in Gold Mining Sodium cyanide is very toxic and an Cyanide in Gold Mining Sodium cyanide is very toxic and an important chemical as it is used to separate the gold and silver particles from the ore.Copper Mining and Extraction Sulfide OresGold, silver, platinum and tin are insoluble in this electrolyte and so do not deposit on the cathode. They form a valuable 'sludge' that collects under the anodes. Soluble impurities of iron and nickel dissolve in the electrolyte, which has to be continually purified to prevent excessive deposition onto the cathodes, which would reduce the purity of the copper.
