Bauxite Beneficiation: An Approach to Value Addition in Mining
Keeping the above characteristics in view, several west coast lateritic bauxite mines of India employ dry crushing−screening process to bring down silica content from the metallurgical grade bauxite Recently, a bauxite mine of Guinea known as AGB2A has also adopted the dry beneficiation procedure to cut down silica from about For 1 t of metal production, approximately 2 t of alumina is required, which is obtained through processing 5–6 t of bauxite ore Large amount of power is consumed for smelting of aluminum, which is mostly provided by coalbased power plants For this, about 8–12 t of coal is needed per ton of aluminum producedBeneficiation of bauxite ores ScienceDirect
