Vedclass · Answer

(A) The process described is known as $hydrometallurgy$. In this process,the ore is treated with a suitable chemical reagent (like an aqueous solution of $NaCN$ or $KCN$ in the case of gold or silver) to dissolve the metal as a complex. This is followed by the recovery of the metal from the solution by adding a more electropositive metal (like $Zn$),which acts as a reducing agent to precipitate the noble metal.

The process of the isolation of a metal by dissolving the ore in a suitable chemical reagent followed by precipitation of the metal by a more electropositive metal is called
