Vedclass · Accepted Answer

It is easier to reduce metal oxides to pure metal than to reduce sulphides or carbonates.

Vedclass · Answer

(B) In the process of metal extraction,it is thermodynamically and chemically easier to reduce metal oxides to pure metal using reducing agents like carbon or through electrolytic reduction compared to reducing metal sulphides or carbonates directly. Therefore,sulphides are converted to oxides by roasting,and carbonates are converted to oxides by calcination before the final reduction step.

Why should metal sulphides and carbonates be converted to metal oxides during the process of metal extraction?
