(D) Calcination is a process of heating an ore in a limited supply of air or in the absence of air to remove volatile impurities and moisture. It is typically used for carbonate or hydrated oxide ores. The reaction $Fe_2O_3 \cdot x H_2O \xrightarrow{\Delta} Fe_2O_{3(s)} + x H_2O_{(g)}$ represents the removal of water of hydration from limonite,which is a characteristic calcination process.
