Question

While extracting metals from sulphide ore,the ore is converted into metal oxides.The process is known as?

Answer 1

It is easy to obtain metals from their oxides. So, ores found in the form of sulphide and carbonates are first converted to their oxides by the process of roasting and calcination. Oxides of metals so obtained are converted into metals by the process of reduction.

Answer 2

the process is ROASTING

- it is heating the ore in excess amount of air / O2

after this the ore is converted into metal oxide
