2015-12-9  The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.

Extraction of Zinc from Zinc Blende Grade 12 Science Notes

Zinc of higher purity can be obtained by electrolysis. Pure zinc rod is used as cathode while a block of impure zinc is used as anode. A mixture of ZnSO 4 and dill H 2 SO 4 is used as electrolyte. On passing current impure zinc dissolves and equivalent amount of pure zinc is deposited at cathode.
