The case of bauxite processing

the chemistry and processing of jamaican bauxitejun , · the chemistry and processing of jamaican bauxite. the first commercial extraction of alumina (al 2 o 3) from bauxite has been attributed to henri sainteclaire deville in about 54. soon after this, in 88, karl joseph bayer described what is now known as the bayer process, which led to a dramatic reduction in the cost of aluminum metal.bauxite bauxite is the main source of the rare metal gallium. during the processing of bauxite to alumina in the bayer process, gallium accumulates in the sodium hydroxide liquor. from this it can be extracted by a variety of methods. the most recent is the use of ionexchange resin.processing of bauxite ores mine engineerprocessing of bauxite ores to obtain aluminum bauxite, the primary aluminum ore, uses the bayer process to extract alumina from the ore. the processing begins with crushing to inch particles and wet screening, to remove some silica fines, which are generally present with bauxite.bauxite processing equipmentthermal processing. we provide custom rotary dryers for drying bauxite, as well as rotary kilns for bauxite sintering applications.. bulk material handling. feeco also provides a comprehensive line of bulk material handling equipment for all of your bauxite handling needs. we offer custom bucket elevators, belt conveyors, reversing shuttle conveyors, and steep incline conveyors, along withmining and refining process world aluminiumunlike 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
