JAMAICA BAUXITE INSTITUTE Page 1 JAMAICA'S BAUXITE & ALUMINA INDUSTRY History of the Industry The commercial production of aluminium began only in the last decade of the nineteenth century, although the existence of the metal in certain kinds of ores was known by scientists from the beginning of that century. However, until World War
Jamaica contains some of the largest known deposits of bauxite in the world. The mining areas are located in the western and central parts of the island. After mining, most of the bauxite is carried to alumina plants where it is refined into alumina. The alumina (or in some cases unrefined bauxite) is carried to export ports by rail.
Jul 30, 2015· In 1974 Jamaica bauxite was the second largest producer of bauxite and the second largest exporter of alumina in the world behind Australia. Over the next ten years, the island that was once the number one exporter of bauxite had fallen to about sixth place and shipping about 7% of the world bauxite production.
This statistic shows the largest producers of bauxite in the world from 2010 to 2018. Russia's bauxite mine production, for example, amounted to some 5.5 million metric tons in 2018.

Production. Red mud is a side-product of the Bayer process, the principal means of refining bauxite en route to alumina.The resulting alumina is the raw material for producing aluminium by the Hall–Héroult process. A typical bauxite plant produces one to two times as much red mud as alumina.
We have a strong track record in designing and building cost-effective, greenfield and brownfield Bayer refining installations. Refinery designs are specifically tailored to the processing characteristics of the bauxite and are optimized to the capital and operating cost environment within which the refinery will be constructed and operated.

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. Achievable extraction efficiencies critically depend on the original concentration in the feed bauxite.

The first commercial extraction of alumina (Al2O3) 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.
The undissolved waste, bauxite tailings, after the aluminium compounds are extracted contains iron oxides, silica, calcia, titania and some un-reacted alumina., approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis.
