Nov 12, 2014· Clay impurities associated with bauxite negatively affect the Bayer process for alumina production. These impurities should be removed as far as possible by a beneficiation technique before the ore is used as feed for the Bayer process. In this current investigation, bauxite washing was conducted in the laboratory.
Unlike ores from base metals, the grade of most bauxite found through mining is acceptable. Bauxites of Brazil, South-East Asia, as well as some types found in Australia and China, need up-grading from the crude ore. This is achieved by washing and screening, and then the super-fine fractions (clayey components) are removed.
