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

The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au(s) + 8 NaCN(aq) + O 2 (g) + 2H 2 O(l)→ 4 Na[Au(CN) 2](aq) + 4 NaOH(aq) . In this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au(CN) − 2 ion.. Application. The ore is comminuted using grinding machinery. . Depending on the ore, it is
