Question

draw a schematic diagram of the various steps involved in the extraction of metals from ores for metals of medium reactivityand for metals in lower reactivity

Answer 1

both of them have to be extracted by roasting...

2HgS+ 2O2 ===> HgO +  SO2

2ZnS + 2O2 ===> 2ZnO + SO2

These oxides can be reduced with coke to form the metal which have to be refined

Answer 2

hope this helps u........
