bauxite mining

The general process of extracting aluminum in industry is as follows: First you need to extract alumina from bauxite. Then the alumina will be changed to aluminum by electrolysis. Now there are mainly three methods for alumina production which include sintering, Bayer and joint method.
However, there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding. Generally we choose SBM crusher or SBM grinding mill to crush the raw materials to be required fineness before used to produce aluminum. Bauxite crushing is relatively simple. Generally we use the professional SBM mining equipments for bauxite crushing. As the leading stone crusher manufacturer and grinding mill  manufacturer, SBM has also been closely following the bauxite mining at home and abroad. SBM has manufactured large amount of mining equipments to global countries, such as jaw crusher series, impact crusher series, cone crusher series and the grinding mill series, etc. SBM mining equipments have been exported to more than 130 countries which are widely applied in mining industry including the bauxite crushing. For decades, SBM has always continued to innovate in the development, production, sales, and service sectors.
