Which method used in metallurgy specifically describes the formation of metal oxides by heating carbonate ores?

Calcination, used in metallurgy, specifically describes the formation of metal oxides by heating carbonate ores. Calcination is the process of heating an ore in the absence or limited supply of air to bring about thermal decomposition or remove volatile impurities. The primary purpose is to convert carbonate ores into oxides, which are easier to reduce to metals.
