| High alumina bauxite?is a natural high bauxite by product after high temperature calcination. Natural bauxite is mainly composed of three kinds of aluminum hydroxide and aluminum silicate minerals. Three kinds of aluminum hydroxide for diaspore (diaspore, gibbsite, boehmite) (boehmite, wave brucite, gibbsite) and gibbsite (water stone, stone, aluminum hydroxide, aluminum hydroxide gibbsite).
Aluminum silicate minerals kaolinite, pyrophyllite, mainly refers to illite etc.. According to the mineral composition, high alumina bauxite is divided into: diaspore kaolinite, kaolinite, gibbsite, boehmite - pyrophyllite, kaolinite and boehmite and diaspore - illite etc.. Natural bauxite is used for calcining refractory raw materials, the main raw material for the production of aluminum powder, and corundum abrasive material and production of aluminate cement. |
