Vedclass · Answer

(B) The process of auto-reduction is used for the extraction of metals like $Cu$,$Hg$,and $Pb$ from their sulfide ores. In this process,the sulfide ore is partially roasted in air to convert a part of the sulfide into its oxide or sulfate. This oxide or sulfate then reacts with the remaining unroasted sulfide ore to produce the metal without the need for an external reducing agent. For example,in the case of $Cu_2S$,the reaction is: $2Cu_2S + 3O_2 \rightarrow 2Cu_2O + 2SO_2$ followed by $2Cu_2O + Cu_2S \rightarrow 6Cu + SO_2$.
