chemical reactions in mining of silver

Silver is a precipitant because it is a new solid substance formed by a chemical reaction between soluble silver nitrate and copper. The balanced chemical reaction looks like: 2AgNO 3 + Cu --> Cu (NO 3) 2 + 2Ag. The reaction continues until one of the reactants is completely consumed in the reaction. Once one of the reactants is gone, the

Silver processing Britannica

Silver is removed by the Parkes process, which consists of adding zinc to the molten lead bullion. Zinc reacts rapidly and completely with gold and silver, forming very insoluble compounds that float to the top of the bullion. These are skimmed off and their zinc content recovered by vacuum retorting.
