The chemical properties of zinc are similar to that of aluminum, so it is usually possible to deduce the chemical properties of zinc (bisexual) by the properties of aluminum.

1, the elemental zinc can react with the acid and can react with the alkali.

2, Zinc Oxide and zinc hydroxide, both acid soluble and alkali soluble.

Production method

The iron sphalerite or sphalerite is calcined into Zinc Oxide in the air and then reduced by carbon (lower purity).

Or mixing Zinc Oxide with coke and heating 1373K~1573K in a blast furnace to make zinc distilled out (purity about 98%);

Or by sulfuric acid leaching into zinc sulfate, controlled by PH, the zinc dissolution of zinc sulfate and iron impurities such as arsenic and antimony hydrolysis precipitation into the leaching slag, adding zinc powder to remove impurities such as copper and cadmium in the filtrate, and electrolytic zinc deposition, which produced high purity zinc (about 99.99%);
