Which of the following statements accurately describe the calcination process in extractive metallur — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Calcination involves heating the ore below its melting point in the absence or limited supply of air (air holes closed). It decomposes carbonates and removes moisture/water of crystallization. Roasting (not calcination) is used for sulphide ores. Neither process is meant to melt the ore.
