Question

Explain calcination method with chemical equations.​

Answer 1

Explanation:

The ore is heated below its melting point either in absence of air or in limited supply. This method is commonly used for converting carbonates and hydroxides to their respective oxides. ... So, calcination is mostly used in the decomposition of limestone (calcium carbonate) to lime (calcium oxide) and carbon dioxide

Answer 2

Answer:

Calcination is a process of heating ore in the absence of air to a high temperature but insufficient to melt the ore. Generally, carbonates and hydrated ores are calcined. Example: ZnCO3 → ZnO + CO2.
