I was inspired to write about the bauxite/alumina industry, primarily in Jamaica, from a recent visit to Discovery Bay, St Ann, where the plant of Discovery Bauxite owned by Atlantic Alumina Company is located and an article by Lance Neita in The Sunday Gleaner, December 12, titled 'An injunction not only on mining but on huge …

The Mining Act of 1947 is the main Jamaican law governing compensation for disturbance of surface rights and damage to land or property as a result of bauxite mining and processing. The law does not cover health impacts or the effects of social...

The mining of bauxite and the processing to alumina impacts on the air and water quality, hence the need for monitoring to ensure that certain standards are achieved.

Bauxite was discovered in Jamaica in the 1940s while processing to alumina began in the early 1950s. Based on currently known bauxite deposits, the Mines and Geology Division predicts that Jamaica's bauxite-alumina industry could last for another 50-100 years.

The social impact of the bauxite-alumina industry on Jamaica's small rural communities has been, for the most part, very hurtful. ... Government inspection of the restoration process was extremely weak. The resulting low farm productivity was the likely reason for the increase in poverty that followed. Furthermore, deficient land reclamation ...

Jamaican bauxites occur 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 mining of bauxite and the processing to alumina impacts on the air and water quality, hence the need for monitoring to ensure that certain standards are achieved.

Minister of Science, Technology, Energy and Mining, Hon. Phillip Paulwell, foresees an inevitable cessation in the export of bauxite, noting that there are more long- term benefits in having it processed here in Jamaica.

The Bayer process uses high-pressure digestion conditions to extract alumina minerals from bauxite [].During the process, a variety of impurities often dissolve and eventually impact the liquor characteristics, alumina yield, and quality, often making the alumina unsuitable for smelter operations [].Traditionally mined Jamaican bauxites are …

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 year was 1996, and the Government of Jamaica was moved to establish a fund for social investment in bauxite communities. By then, the island's bauxite industry had developed significantly from the discovery of premium ore in 1938 and the subsequent start of commercial scale processing for export in 1952.

Jamaica's bauxite resources were recognized in 1939 and with focused development work in overcoming processing challenges, commercial bauxite mining started in Jamaica in June 1952. By 1958 Jamaica was the world's leading bauxite producer (Roberts 1971 ).

processing challenges and refineries must explore adaptations to the processing of these more difficult bauxites. The practical approach would be to blend the lower grade bauxites with the Jamaica-1 bauxite to maintain a consistent bauxite feed, however this investigation presents a case study in processing the worst-case type of bauxite blends.

The Bayer process which is used to extract alumina from bauxite, had to be modified to deal with Jamaican bauxite. The sources of pollution in this process and ancillary processes which provide inputs or remove outputs of the Bayer process are briefly described. The process technology is geared towards a single pro duct and virtually a …

The topics covered by this study are: the bauxite-alumina industry's history, the evolution of its regulatory framework, the impacts of bauxite mining and processing on Jamaican society, public health and the natural environment, and the …

Jamaica bauxite or bauxite in Jamaica was first shipped in 1952. By 1957 Jamaica was the leading bauxite producer in the world. In 1961 there were four companies mining bauxite in Jamaica. The companies were Reynolds, Alcan, Kaiser and Alcoa. Jamaica was planning its Independence from Great Britain on August 6, 1962. The …

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 …

American aluminum corporations incorporated Jamaican bauxite into the globalized maze of mines, refineries, and smelters. The island's proximity to North America, along with the availability of suitable sites for ports, made it ideal for investment in this mineral. By 1957, Jamaica was the world's largest producer of bauxite and this ...
