Bauxite

[Product Specifications]: Various specifications of sand and powder

[Production capacity]: 80,000 tons

[Scope of application]: Bauxite is mainly used in electrode, flux, aluminum smelting industry, precision casting, refractory products, aluminum silicate refractory fiber, alumina cement, etc.

【product description】:

Bauxite (aluminous soil; bauxite), also known as bauxite or bauxite, is divided into raw bauxite, cooked bauxite, and can also be divided into converter bauxite, shaft kiln bauxite, and down flame kiln bauxite. According to the particles can be divided into two kinds of aggregate and powder. The main component is alumina, which is a hydrated alumina containing impurities and is a soil-like mineral. White or off-white, brownish yellow or light red due to iron. The density is 3.9 to 4 g / cm3, the hardness is 1 to 3, opaque and brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. ...
