Question

what is calcination......????​

Answer 1

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.

Answer 2

Answer:-

As per the popular definition, calcination is defined as the process of converting an ore into an oxide by heating strongly. The ore is heated below it's melting point either in absence of air or in a limited supply. This method is commonly used for converting carbonates and hydroxide to their respective oxides. During calcination, moisture and volatile impurities are also removed .

Calcination can also be described as a thermal process that is used to convert ores or other solid materials by bringing about thermal decomposition. In calcination, reaction most of the time occurs at or above the thermal decomposition temperature
