Question

what are the various steps involved in the extraction of a metal lying in the middle of the activity series​

Answer 1

There are two methods by which extraction of metals from the middle of the Activity Series can take place.

Roasting

Roasting is the process of converting the carbonates and sulphides of the ores into oxides through the process of supplying heat.

2HgS + 4O2 --------> 2HgO + SO2

Calcination

After the process of roasting, calcination takes place. It is the process of supplying excess heat in order to reduce the metal oxides into their respective metals. This takes place in the presence of carbon.

ZnO + C ----> Zn + CO

Hope this helps you! Good luck for the boards!
