Processing Bauxite In Jamaica

The Chemistry and Processing of Jamaican Bauxite

The Chemistry and Processing of Jamaican Bauxite The first commercial extraction of alumina (Al 2 O 3 ) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal.

Jamaicas Bauxite And Alumina Industry

Reynolds began ex­porting bauxite from Ocho Rios in June 1952, and Kaiser followed a year later from Port Kaiser on the south coast. Alcan built the first alumina processing plant near its mines at Kirkvine, Manchester, and in early 1952 began shipping alumina from Port Esquivel. This was the beginning of the industry in Jamaica.

Bauxite Jamaica - A Jamaica Experience

Jul 30, 2015 · Bauxite Ore from mining in Jamaica. The Bayer Process is the main industrial way of refining bauxite to produce aluminum. Bauxite is the most important ore in aluminum but it has only thirty (30) to fifty-four (54) percent aluminum oxide. The remaining mixtures to produce aluminum are titanium dioxide, silica, and other iron oxides.

Mining and Refining – Process

Alumina is used for the production of aluminium metal, through the Hall–Héroult electrochemical smelting process. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production.

Bauxite - Wikipedia

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 ion-exchange resin.
