ã€China Aluminum Network】 Mine is a mineral resource we are more familiar with. Bauxite ores are used in a variety of applications, of which the more important ones are: aluminum in the aluminium industry, as refractory and abrasive materials, and as a raw material for high-alumina cement. Ore uses are different, their quality requirements vary. Table 3.9.1 is the industry standard for bauxite ore issued by the China Nonferrous Metals Industry Corporation in 1994 (YS/T78-94). According to the standard, bauxite is divided into three types of sedimentary diaspore, stacked diaspore and lateritic gibbsite, and divided into LK12-70, LK8-65, LK5- according to chemical composition. 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50, LK3-40 and other nine brands. In addition to the provisions on the chemical composition of bauxite, the standard also requires that the water content of the deposited dicalite should not exceed 7%, and the moisture content of the deposited dicalite and laterite type gibbsite should not exceed 8%. . In addition, the grain size of bauxite ores must not exceed 150mm. Bauxite ore may not be mixed with dirt, limestone and other debris.
