Abstract. Bauxite is the major alumina (Al2O3) bearing ore used in the aluminum manufacturing industries. The bauxite containing less than 50% Al2O3 is called low-grade bauxite ore which is commonly used for the alumina-based abrasives and refractories productions. The alu-mina-silica and alumina-ferrite complexes are the fore-most …

01 Flotation Process. Flotation method is the process that uses the difference of physical and chemical properties of the surface of the target mineral for separation. It is one of the main methods for processing magnesite at present. The impurities in magnesite can be roughly divided into silicate and carbonate.

involves the separation of iron minerals from low-grade iron ores. There are three basic methods for separation of iron minerals i.e., magnetic separation, froth flotation and gravity concentration [4]. The iron concentrate produced by any processing method is used for producing iron metal either by blast furnace or direct reduction methods [5].
