Product Description

Product Description:

bauxite, alumina or bauxite miner , main ingredients are aluminum oxide, hydrate alumina containing impurities,

is an earthy mineral.White or grey, brown yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3, opaque, very brittle.

Very difficult to melt.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution.Mainly used for aluminium, refractory material.

Application:

1) The bauxite for aluminum industry in defense, aerospace, automotive, electrical, chemical, and daily supplies.

2) Bauxite clinker processed into fine powder and made after the casting mold. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sector.

3) The bauxite can be used in refractory products. The refractoriness of high-alumina clinker is up to 1780 ℃. Its features are chemical stability strong, and physical properties of sound.

4) It can be raw material for alumina cement, abrasive materials and aluminum compounds.
