What is the role of zinc metal in the extraction of silver?

During extraction of silver, the finely powdered silver ore is treated with dilute KCN solution to form a cyano complex of silver. This complex is water soluble. A g 2 S 4 N a C N ⇌ 2 N a A g C N 2 N a 2 S Then zinc is added to the solution. More electropositive zinc displaces silver from the complex. 2 N a A g C N 2 Z n N ...Rna Extraction Kit - Rna Extraction KitRna Extraction Kit.
