احصل على السعر· Bauxite is a sedimentary rock that consists mainly of the basic aluminum oxide mineral gibbsite [aluminum hydroxide, Al(OH)3], and the dimorphic minerals böhmite and diaspore [both basic aluminum oxide, AlO(OH)]. Lesser amounts of the iron oxides goethite [FeO(OH)] and hematite [Fe2O3] impart bauxite's reddish hue. Bauxite is named for the French locality of Les BauxdeProvence, .
احصل على السعرThe alumina content of bauxite ores varies from one deposit to another, and methods of treatment differ accordingly (see ). This means that each alumina plant is almost tailormade to suit a particular bauxite. The processes are nevertheless basically similar, and a general description is given in the following. The bauxite from the mine is crushed and ground. It is then mixed with a ...
