(D) The leaching of silver ore $(Ag_2S)$ is a process of hydrometallurgy where the ore is treated with a dilute solution of sodium cyanide $(NaCN)$ in the presence of air (oxygen) to dissolve the silver as a complex.The chemical reaction is: $Ag_2S + 4NaCN \xrightarrow{Air} 2Na[Ag(CN)_2] + Na_2S$.The silver is then recovered from the complex by displacement using zinc dust: $2Na[Ag(CN)_2] + Zn 	o Na_2[Zn(CN)_4] + 2Ag \downarrow$.
