Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue silvery appearance when oxidation is removed. It is the first element in group 12 of the periodic table.In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state +2, and the Zn 2+ and Mg 2+ ions are of

Zinc is mined both at the surface and at depth. Surface mining of zinc, typically used for oxide ores, while underground mining yields zinc sulfide ores. Some ofmon methods of zinc mining are open pit mining, open stope, and cut and fill mining:
Open pit mining: Surface mining involves the removal of waste rock from above an ore deposit before it can be extracted. Once the waste overburden is removed, ore and waste are then mined in parallel, pri
Underground Development and Extraction Levels. The general practice of the field, except where the lode is narrow, is to place the extraction levels in settled country, at a safe distance from . the lode on the foot wall side.

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.
pumped to a second facility, a solvent extraction process then transforms resultant zinc chloride into zinc sulfate, which is passed across electrowinning cells that separate sulfate molecules from zinc atoms.
Lead and zinc ores are mined mostly by underground operations as themon form of mineralization are veins where an association of different minerals can be found.
