Bauxite tailings, also known as red mud, red sludge, bauxite residue, 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).

Also, Guyana's exports: BAUXITE PROCESSING IN JAMAICA AND GUYANA 285 GDP ratio is larger than that of Jamaica, providing a relatively larger base with which to calculate the percentage impacts. Finally, Guyana's import coefficients are generally larger than those of Jamaica, further depressing the net foreign exchange impact.
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.
60 years of bauxite mining in Jamaica - Part 1 | News ...
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.
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.

Alumina Partners of Jamaica (ALPART) has its bauxite mining and alumina processing plant located at Nain, St. Elizabeth, in the south of Jamaica. The company was first established in the early 1960s under the union of three companies (Anaconda, Kaiser Aluminum and Reynolds Metals).
Jamaica has natural resources, primarily bauxite, and an ideal climate conducive to agriculture and also tourism.The discovery of bauxite in the 1940s and the subsequent establishment of the bauxite-alumina industry shifted Jamaica's economy from sugar and bananas.By the 1970s, Jamaica had emerged as a world leader in export of these minerals as foreign investment increased.

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.
Alcan built the first alumina processing plant near its mines at Kirkvine, Manchester, and in early 1952 began shipping alumina from Port Esquivel. This was the beginning of the industry in Jamaica. After the first shipment of bauxite from Jamaica in 1952, production increased rapidly, and by 1957 Jamaica had become the leading bauxite producer ...
TENORM: Bauxite and Alumina Production Wastes | US EPA
The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
More Benefits in Processing Bauxite Locally – Mining ...
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. Mr. Paulwell said there are telling examples now emerging worldwide, where some ...
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.

Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.
