45%-60% Bauxite



Best Quality Raw Metallurgical grade Bauxite Ore Alumina AI2O3 45-60% (Al2O3 45%-60%)

Bauxite contains 50~60% alumina (also known as alumina), and bauxite is the raw material for manufacturing aluminum and an important raw material for manufacturing artificial corundum, bauxite cement, and refractory materials. Aluminum is the third most abundant element on earth, after oxygen and silicon.

Description of Bauxite

Bauxite main component is alumina,which is a hydrated alumina containing impurities and is a kind of earthy mineral.White or off-white,brown or light red due to iron. Density 3.45g/cm3,hardness 1-3,opaque,crisp.Extremely hard to melt..Insoluble in water,soluble in sulfuric acid,sodium hydroxide solution. It is mainly used for aluminum smelting and refractories.

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.
