Question

in what form the calcined ore is obtained and how it can be reduced give chemical equation of the reduction process involved for the example given by you​

Answer 1

Answer:

(Firstly it’s carbonate ore , the process involved is called calcination )

First step is removing major physical impurities through various process called ‘Enrichment of Ore’

Now, ‘Conversion to oxide’ :

For example :

CaCO3.MgCO3 -> CaO + MgO + CO2

This (CaCO3.MgCO3) is called Dolomite and it is ore of calcium and Magnesium both.

The process takes place in limited amount of air in Reverberatory Furnace.

After conversion into oxide the next step involved is ‘Reduction’:

MgO + C -> Mg + CO

Now, the metal undergo ‘Electrolytic refining’ :

Where anode is impure metal, cathode is pure metal and acidified salt solution of metal is taken as electrolytic solution.

After all these steps metal is extracted from its ‘Carbonate ore’.
