Bauxite ore has a variety of uses, and its quality requirements vary depending on the ore use.
Bauxite ores are divided into gibbsite type, diaspore type and diaspore type according to the main aluminum-containing minerals they contain. Foreign bauxite ores are mainly gibbsite type, followed by diaspore monohydrate, and diaspore bauxite type is very rare.
However, in China, it is mainly diaspore bauxite, and gibbsite bauxite is very rare. Foreign gibbsite bauxite has the characteristics of high alumina, low silicon, and high iron, and the ore is suitable for Bayer processing with low energy consumption. The overall characteristics of diaspore monohydrate in China are high alumina, high silicon, low sulfur and low iron, medium and low aluminum-silicon ratio, poor ore quality, difficult processing, and high energy consumption for alumina production.
2. Uses and technical and economic indicators Bauxite ore has a variety of uses, the most important of which are: refining metal aluminum in the aluminum industry, as refractory materials and abrasive materials, and as raw materials for high-alumina cement.
The industry standard for bauxite ore (YS T78-94) issued by China Nonferrous Metals Industry Corporation in 1994. According to this standard, bauxite is divided into three types: sedimentary diaspore monohydra, stacked diaspore and lateritic diaspore, and is divided into nine grades such as LK12-70, LK8-65, LK5-60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40 according to the chemical composition. In addition to stipulating the chemical composition of bauxite, the standard also requires that the moisture of sedimentary diasporite monohydrate shall not be greater than 7%, and the moisture content of stacked diaspore monohydrate and lateritic gibbsite shall not be greater than 8%.
In addition, the particle size of bauxite is required not to be greater than 150mm. Bauxite ore shall not be mixed with mud, limestone and other debris. In the industrial extraction of metallic aluminum, alumina is first extracted from bauxite, and then the alumina is electrolyzed into metallic aluminum.
