Vedclass · Answer

(A) Calcination is a process of heating an ore in a limited supply of air or in the absence of air to a temperature below its melting point. $1$. Carbonate ores decompose to form oxides (e.g.,$ZnCO_3 \rightarrow ZnO + CO_2$). $2$. Moisture and volatile impurities are removed. $3$. The process is kept below the melting point to prevent fusion. $4$. Option $A$ is incorrect because the removal of impurities as elemental vapours is characteristic of roasting or specific distillation processes,not calcination. $5$. Option $D$ is incorrect because calcination does not involve oxidation; in fact,it is often used for ores that are already in the desired oxidation state or to remove volatile components.
