Zn: Zinc

Abundance: 76.0ppm(in the earth's crust)

Bake sphalerite and/or wurtzite.

2ZnS + 3O2 right 2ZnO + 2SO2 right

down

Reduce zinc oxide by baking with coke.

ZnO + 3C right Zn + CO right


Method 2

Add smithsonite into hot sulfuric acid.

ZnCO3 + H2SO4 right ZnSO4 + CO2 right

down

Crystallize zinc sulfate and make purity higher. Silver is recovered from residue.

ZnSO4

down

Dissolve crystals of zinc sulfate, and apply electrodialysis.
