- Jan 19, 2018-

Bauxite is a kind of industrial clay, is a kind of non-metallic minerals whose Mohs hardness is between 1 to 3, is composed of very fine crystals, is shaped of stone block and relatively hard and dense. It has the function of high temperatures resistance. Bauxite is the raw material of high alumina refractory material white fused aluminum oxide, brown corundum, black corundum and other production, but also the most commonly used raw ore for smelting aluminum and producing refractories, the main component is aluminum oxide, is impurities containing the hydrated aluminum oxide, is a Soil-like mineral. Density 3.9 ~ 4g / cm3, and it's extremely difficult to melt, insoluble in water, soluble in sulfur. The usage of bauxite is wildly, it can be used in chemical industry, building materials, refractories, iron, steel and other industries.
