Question

Carbonates and sulphide ores are usually converted into oxide during the process of extraction

Answer 1

Carbonates and sulphide ore are usually converted into oxides during the process of extraction because it is easy to extract metal from its oxide ore by reduction reaction when compared to carbonate or sulphide ore. Obtaining a metal from its oxide is much easier than doing that from a metal sulphide and carbonate.Oct 15, 2017
