Bauxite Ore Mining/ Calcined Bauxite/ Alumina Calcium for Refractory Industry Bauxite Product (Al2O3 70%-80%)

70%-80% Bauxite



Bauxite Ore Mining/ Calcined Bauxite/ Alumina Calcium for Refractory Industry Bauxite Product (Al2O3 70%-80%)

Bauxite is also called bauxite or bauxite. Its main component is aluminum oxide, which is hydrated alumina containing impurities. It is an earthy mineral. White or off-white, brown or light red due to iron content. The density is 3.9~4g/cm3 and the hardness is 1~3. It is opaque, brittle, extremely difficult to melt, insoluble in water, and soluble in sulfuric acid and sodium hydroxide solutions. Mainly used for smelting aluminum and making refractory materials.

Description of Bauxite

The bauxite referred to in the refractory industry usually refers to bauxite ore with a calcined Al2O3 content of ≥48% and a low Fe2O3 content.

Characteristics of Bauxite


Ferrosilicon furnace is an industrial electric furnace that consumes a lot of power and is a type of submerged arc furnace. Ferrosilicon furnace includes furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressure release and lifting system, loading and unloading system, controller, burn-through device, hydraulic system, transformer And various electrical equipment, etc., the use of refractory materials is also quite demanding.


In 2006, Our factory was founded in Yuzhou, the raw material base.High bauxite ore is a finely divided colloidal mixture composed of aluminum hydroxides and various ratios. High-alumina bauxite in the refractory industry usually refers to bauxite ore with a calcined Al₂O₃ content greater than 48% and a low Fe₂O₃ content.
