1. Introduction
Bauxite is a non-plastic clay mineral, also known as high bauxite or bauxite. The main minerals are gibbsite ( AL2O3 · H2O ) and gibbsite ( AL2O3 · 3H2O ). Bauxite is not a mineral name, but a mixture of diaspore, diaspore and gibbsite. Its main component is AL2O3, generally 40 % ~ 80 %, and SIO2, TIO2, FE2O3, CAO, MGO, K2O, NAO, etc. Mainly oolitic, bean, debris, and mud, soil, etc. Color from white to ochre, generally high iron red, low iron gray white. China is rich in bauxite deposits, most of which are monohydrate bauxite. It is characterized by high alumina and silica content and low iron content, which is most suitable for the production of high alumina refractory. According to different uses, bauxite can be divided into metallurgical grade, refractory grade, grinding grade, chemical grade, cement grade and so on. Bauxite is the main material of bauxite cement, refractory and artificial abrasive. It is also an important ore for refining alumina, metal aluminum and aluminum alloy.
