Question

write the steps involved in the extraction of pure metals in the middle of the activity series from their carbon carbonate ores

Answer 1

calcination I Hope this will help u

Answer 2

Welcome dear,

● Steps involved -
- To extract pure metals from its carbonate ore, we first heat the ore at high temperature in absence of air. This is called calcination.
CuCO3 + heat → CuO + CO2

- Metal is then displaced from its oxide with the help of reducing agent. Most commonly carbon, aluminium are used for this purpose.
CuO + C → Cu + CO

- Impure metal thus obtained is refined using electrolysis.

Hope this helps you...
