Bauxite Ore Extraction Process

Bauxite Ore Extraction Methods

Bauxite is mined almost exclusively in surface operations. The most important and often used surface mining methods used to extract iron ore are open-pit and open-cut methods. There are also underground mining method for bauxite according to ore property and geography. The decision to choose underground or surface mining techniques is dependent on the proximity of the ore body to the surface. Historically, underground mining methods, including caving and stopping, were commonly used to extract bauxite ores.

Bauxite Ore Extraction Process

The bauxite ore extraction depends on the ore quality and composition. Most bauxite is mined as the sulfide; lower grade ores are concentrated by froth flotation, while higher grade ores are heated to 500иC600буC, the temperature at which stibnite melts and is separated from the gangue minerals. Bauxite can be isolated from the crude bauxite sulfide by a reduction with scrap iron. The sulfide is converted to an oxide and advantage is often taken of the volatility of bauxite oxide, which is recovered from roasting. This material is often used directly for the main applications, impurities being arsenic and sulfide. SBM is a professional bauxite extraction plant and mining equipment supplier.
