Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).
The Jamaica Bauxite Institute (JBI), during 2005/2006 fiscal year, continued work aimed at protecting bauxite lands and reserves, including a submission to Cabinet for the establishment of the Bauxite Land Management Committee, to provide for the effective management of bauxite-bearing lands.
Time trends in bauxite reserve discoveries each year for period 1900 to 2000. Data from CRC 525 database. resource depletion even with increase in bauxite pro-duction rates of 5% (F ig. 5).
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.
Jamaica's Natural Resources Bauxite. Interest in Jamaica's bauxite deposits began in the 1940s through development and exploration by the Alcan, Reynolds, and Kaiser Companies. The newfound interest in Jamaica's Bauxite deposits was sparked by an increase in global demand for aluminium during and after World War II.

At one of the disposal sites in Jamaica, the bauxite residue had been deposited in depressions left after bauxite mining. When deposited, the residue had a solids content of approximately 20% but it was discharged in a way that in most cases, when full and aged, no residual pond water remained resulting in a relatively dry surface with a pH of about 11.
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.
The country with the highest amount of bauxite reserves worldwide in 2019 was Guinea. In that year, the reserves of bauxite in Guinea amounted to about 7.4 billion metric dry tons.

Bauxite is the most important aluminum ore. This form of rock consists mostly of the minerals gibbsite Al(OH) 3 , boehmite γ-AlO(OH), and diaspore α-AlO(OH), in a mixture that usually includes the two iron oxides goethite and hematite , and may include the clay mineral kaolinite , and small amounts of the titanium minerals anatase TiO 2 , Ilmenite , FeTiO 3 , and FeOTiO 2 .
In the story entitled ‘Jamalco to acquire more lands for mining’, published June 11, 2014, ... (CAP), the minority partner in Jamalco with a 45 per cent stake, confirmed the general plan to seek out new supplies of bauxite ... The mining company said that any land it purchases in Jamaica is for the sole purpose of mining bauxite.

island to explore for bauxite, acquire reserve lands, and set up mining operations. On June 5, 1952 the first shipment of bauxite was made by Reynolds Jamaica Mines from its port in Ocho Rios to the parent company’s alumina plant at Hurricane Creek, Arkansas. Kaiser followed a year later, shipping bauxite from Port Kaiser on the south coast.
In February 2009, Jamaica hosted the Metal's Bulletin 'Bauxite and Alumina Seminar' at Rose Hall in St James. It was reported that "Jamaica was chosen to host the seminar for a reason. The country is one of the world's main producers of bauxite and alumina, and has an ideal location between two markets - consumers in North America and Europe and suppliers in South America and Africa.
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.
Jamaica's bauxite reserves are large, exceeding 1.5 billion tons. At the present rate of extraction, reserves could last another 150 years. Jamaica's bauxite is not extremely alumina pure; one ton of Jamaican bauxite contains only about 0.4 tons of alumina.

Bauxite mining is considered to be one of the most significant reasons behind deforestation in Jamaica. During the last decades, large areas of forest have been cleared on the island due to open pit mining for bauxite.
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 and development of one of its prime mineral resources.
