The process was invented in 1888 by an Austrian, Karl Joseph Bayer. Bayer discovered that when bauxite was mixed with caustic soda, the alumina content in the bauxite would dissolve and separate itself from the other components, such as iron and silica, which would remain in …
In October, 1943, Alcan was incorporated under the name Jamaica Bauxites Limited as a Jamaican company to investigate the commercial potential of Jamaican bauxite. In the same year, 2500 tonnes of ore was shipped to the USA for process investigation and it was realised that the bauxite was suitable for processing using Bayer technology.
The commercial possibilities of Jamaican bauxite were recognized in 1943 at a time when there was great need for aluminum for the Allied war effort, and when availability was being made difficult by the harassment by German U-boats of Allied bauxite ships plying from the sources of the ore in South America to the North American mainland.
Alumina is extracted from bauxite by the Bayer process. The waste slurry generated in this process is called red mud and its solid fraction is called bauxite residue. ... and a pilot-plant study performed by Japanese Scientist at the Jamaica Bauxite Institute (JBI) has shown that the REE can be successfully extracted. In Red-Mud the total REEs ...
The Jamaica Bauxite Institute (JBI) is a recognized repository of information on bauxite and alumina, and enjoys a solid reputation for research and analysis of data and trends in the industry. ... Promoting research and development …

This experiment investigated three major parameters characterizing some of the poorest grade bauxite available: % reactive silica, % aluminous goethite and % boehmite content. Four blends
Jamaican bauxite deposits can broadly be classified into two types, catchment and hillside, depending on their form and topographic setting. The major iron phase in catchment deposits is hematite ...
A concession from the Government of Jamaica permits Noranda Bauxite Limited to mine bauxite in Jamaica through 2030. Bauxite is mined at St. Ann and the ore is transported via railway to Port Rhoades. There, it is dried and shipped to its customers.

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.

These corporations controlled about 10% of Jamaica's land and at the time paid a mere shilling a ton – about 20 cents per ton – for bauxite extraction. In 1952, the first shipment of bauxite was exported from Jamaica, and the first batch of alumina was processed in Jamaica.
The mining of bauxite in Jamaica is primarily an open-pit extraction process. The topsoil is removed, and the bauxite ore is extracted using heavy machinery, such as excavators and bulldozers. The extracted bauxite is then transported to refineries for processing into alumina.
Jamaican bauxite occurs as pocket or blanket deposits of red earthy material on the karst surface of the Tertiary White Limestones, mainly in the interior of the island. The contact between the bauxite and the limestone is sharp, with a …
Jamaica's bauxite occurs in a series of deposits across the middle of the island, east to west. The largest deposits are in the parishes of St. Ann, Manchester, St. Elizabeth, and Trelawny, with smaller deposits in Clarendon and St. Catherine.
Jamaican bauxite occurs as pocket or blanket deposits of red earthy material on the karst surface of the Tertiary White Limestones, mainly in the interior of the island. The contact between the bauxite and the limestone is sharp, with a strong colour contrast between the dark red bauxite and the white limestone.
Bauxite mining began in Jamaica in the early 1950s. Bauxite was first exported by Reynolds Metal Company. Shortly after this, Kaiser and Alcan also set up mining operations and began exporting bauxite and alumina. After these first shipments, production increased rapidly, and within five years Jamaica had become the leading producer of bauxite ...
1. Transform Jamaica Bauxite Institute. Reimagining the JBI as the Jamaica Minerals Institute would expand its mandate to include research, exploration, and production of minerals such as limestone and rare earth elements. This transformation could also be aimed at positioning Jamaica as a leader in sustainable mining and refining practices. 2.
