Bauxite Beneficiation: An Approach to Value Addition in ...

2021-7-2  Abstract. 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.

PROCESS FOR DRY BENEFICIATION OF BAUXITE

What is claimed is: 1. A method for beneficiation of bauxite ore, comprising: providing a source of bauxite ore; drying the bauxite ore to achieve a moisture content of less than about 4.0% by weight, and preferably less than about 2.0% by weight; and separating the bauxite ore with a triboelectric electrostatic belt-type separator or belt separator system (BSS) to generate a bauxite rich ...

2017-2-1  However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability. These deposits usually have a beneficiation plant that washes the bauxite and sends the high silica fines (kaolinite and/or quartz) to a tailings dam prior to ship loading the bauxite.
