Bauxite Beneficiation Efficient Way to Remove Silica in Bauxite

Aug 12 2022The main component of bauxite is Al 2 O 3 containing a small amount of Fe 2 O 3 SiO 2 and other impurities. The main objective of bauxite beneficiation is to lower the concentration of reactive silica and also to increase the alumina content. In addition bauxite beneficiation can also be used for iron extraction or iron removal.

Bauxite Beneficiation An Approach to Value Addition in Mining

The main objective of bauxite beneficiation is to lower the concentration of reactive silica in the form of kaolinitic clay and also to increase the alumina content. Additionally reduction in iron content particularly in the form of goethite and reduction of organic carbon can also increase the value of the bauxite product. Metallurgical bauxite is a lowvalue bulk ore and therefore

Bauxite Beneficiation Flotation Silica Iron Separation from Bauxite

Because the desired product is a high purity Al2O3 the remaining oxides in the bauxite (Fe2O3 SiO2 TiO2 Organic material) are separated from the Al2O3 and rejected as alumina refinery resides (ARR) or red mud. In general the lower quality the bauxite (ie lower Al2O3 content) the more red mud is generated per ton of alumina product.
