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.
Most of Jamaica's bauxite is red or reddish-brown, a peculiarity which indicates the occurrence of iron mineral in the ore. There is no overburden covering the bauxite, as is the case in many other countries. The ore lies on the surface and is relatively easy to mine. The mining laws of Jamaica require the mining

Alcan built a second refinery in Jamaica at Ewarton, St. Catherine, in 1959. In 1961, a fourth company, Alcoa, began mining bauxite in the island. The production of alumina also increased, especially after the mid-1960s. By 1968, Alcan had brought the capacity of its two refineries to more than 1 …
The Uses of Bauxite in Jamaica Now, given that bit of the history of the bauxite industry will give you an appreciation of the main purpose of bauxite in Jamaica. This main purpose that I speak of is exportation. Yes, the main purpose of mining the bauxite from the earth is to export it to foreign countries where it will be converted to aluminium.

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. The existence of the JBI puts Jamaica in the position of being one of the few developing countries with an institution devoted solely to the research ...
Alcan (now Rio Tinto) has had a long history in Jamaica, constructing two alumina refineries there in the 1950s. In 2001 Alcan sold its bauxite mining and alumina plants in Jamaica but kept responsibility for many of the bauxite residue sites with the intention of safely remediating them to an agreed standard and transferring ownership to the Government of Jamaica.
Carlton E. Davis, Contributor. ALTHOUGH I have written about the Jamaican bauxite and aluminium industry in three books and numerous articles, I think it is appropriate to repeat some of what I have written to mark the 60th anniversary of the beginning of the commercial mining of the ore.
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. The process stages are: The bauxite is washed and crushed, reducing ...
Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).
Bauxite is the ore from which aluminium is made. 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 the red dirt found in countries like Jamaica, Guyana, Suriname within the Caribbean but also in other countries such as Australia and Brazil.
