Question

explain the process of extraction of metals from the carbonate ore​

Answer 1

Answer:

The process of extraction of metals from their carbonate ores by heating below their Melting point in the absence of air is known as Calcination.

Ex: CaCO3-> CaO+ CO2

Answer 2

Answer:

1.

the first process is calcination - in this process the ore is heated in the absence of oxygen and converted into oxide ore with evolution of CO2 gas

CaCo3 ----heat-->CaO + CO2

2. the second process is reduction - in this process the oxide ore is reduced with suitable reducing agent to get pure metal.

CaO + c -----> Ca + CO
