zinc is extracted from zinc blende by from few processes...
at first the concentration of zinc blende ore is to be purified so that if there is any unwanted dusty particles like gangue , I should be thrown out it may be done by the process of # fourth flotation process #
after that the zinc blende ( ZnS) is to be heated in the presence of air that is Oxygen below its melting point by the process of *roasting. *
2ZnS + O2 --------->2ZnO + S2
heat
after that Zno is to be reduced by the process of reduction with coke so that appears in would be isolated
Zno + C -------> Zn + CO 2
.
hope it help you
