(D) The extraction of silver involves several methods:$1$. Silver is obtained as a byproduct during the electrolytic refining of copper.$2$. The Parkes process is used to remove silver from lead using $Zn$.$3$. The Mac-Arthur Forrest cyanide process involves the reaction: $Ag_2S + 4KCN \rightarrow 2K[Ag(CN)_2] + K_2S$,followed by displacement with $Zn$: $2K[Ag(CN)_2] + Zn \rightarrow K_2[Zn(CN)_4] + 2Ag$.$4$. Heating $Na[Ag(CN)_2]$ does not yield metallic silver; instead,it decomposes into complex products. Therefore,this is not a method for silver extraction.
