Alton T. Tabereaux, Ray D. Peterson, in Treatise on Process Metallurgy: Industrial Processes, 2014 2.5.1.1 Impact of Different Bauxites on the Bayer Process. The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9. The sinter process is widely used to process the poor-grade diasporic …
Alumina extraction from coal gangue could offer an alternative to bauxite as a source of alumina. Mechanically modification by grinding is an effective activation method to improve alumina recovery from coal gangue. The effect of grinding on coal gangue, however, had not been investigated systematically.

High-alumina fly ash microbeads and steel slag were used as main raw materials to synthesize feldspar porous ceramics via high-temperature solid phase sintering by adding pulverized coal as a pore-forming agent. The effects of the steel slag and pore-forming agent on the apparent porosity and flexural strength of porous ceramics were investigated.
Bauxite is also called alumina, and its main components are diaspore and kaolinite. The bauxite in nature contains many impurities. The treatment of low grade bauxite needs to go through the ore washing, grinding and ore dressing processes, which can improve the aluminum content, and then it can be applied in aluminum smelting.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
