Vedclass · Answer

(B) The extraction of metals from their sulphide and carbonate ores is difficult because these compounds are chemically stable and do not easily release the metal. However,metal oxides are much easier to reduce to pure metal using reducing agents like carbon or through electrolytic reduction. Therefore,sulphide ores are first converted into oxides by roasting (heating in the presence of excess air),and carbonate ores are converted into oxides by calcination (heating in the absence or limited supply of air).
