Question

carbonate and sulphide ores are usually converted to oxides during the process of extraction​

Answer 1

Answer:

Explanation:

carbonate and sulphide ores are usually converted to their oxides as this makes the process of extraction more easier .

The oxides can be easily reduced and we can get the metal.

For example :

Zinc glance is an ore of zinc (ZnS) .

It enriched by froth flotaion and is reduced to zinc oxide .

According to the equation

2ZnS +3O2 ----------> 2ZnO+2SO2

The zinc oxide thus obtained can be easily reduced to Zinc by heating it with carbon in the furnace.

ZnO+C---------->Zn+CO.

The conversion of metal carbonates and sulphides to metals is very difficult and economically, it is worst. But metal oxides to metal conversion is easy. So they are converted to oxides.
