bauxite ore mining and processing

Unlike the base metal ores bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade Ore quality can be improved by relatively simple and inexpensive processes for removing clay known as “beneficiation” which include washing wet screening and mechanical or manual sorting
