Answer

(d) Carbonate and sulphide ores are usually converted into oxides during the process of extraction.

It is not easy to reduce naturally occurring carbonate and sulphides directly into metals. 

  • The process involves extra steps and is not commercially viable
  • Hence, they're first converted into oxides

After an ore is converted into oxide, it is easier to reduce them into pure metals.
