The microstructure of bauxite determines to a significant extent the opportunities for its beneficiation and optimum processing downstream. Adequate fine grinding commensurate with its microstructure may result in proper mineral liberation and grain size distribution required for effective ore dressing (i.e. H/M or magnetic separation) and digestion respectively.
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
2019-2-20 · Bauxite Mining Processing. Bauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum. Bauxite is one of the most abundant elements on earth and contains nearly 25-30% of alumina. Its typically found near the equator in tropical and subtropical regions, in the form of horizontal layers beneath a few meters of overburden.
2009-8-1 · 1. Introduction1.1.. ScopeThis document will critically review existing and potential processes for the processing of high silica bauxites. High silica bauxites are usually considered to be those with reactive silica contents in excess of ∼. 8% by weight of the bauxite (reactive silica is defined later in this paper).. This review is limited to bauxites as feedstocks for the processes.
