Vedclass · Answer

(C) Calcination is the process of heating an ore strongly below its melting point in the absence or limited supply of air. It is primarily used to convert metal carbonates and hydroxides into their respective oxides. For example: $CaCO_3 \xrightarrow{\Delta} CaO + CO_2 \uparrow$ $CuCO_3 \cdot Cu(OH)_2 \xrightarrow{\Delta} 2CuO + H_2O \uparrow + CO_2 \uparrow$ Thus,the product obtained is a metal oxide.

In the isolation of metals,the calcination process usually results in:
