Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the ...

It is important to note that smelting of all bauxite domestically mined would have amounted to annual production of about 365,000 tons of aluminum for Guyana, or the annual output of one medium-sized smelter. Due to Jamaica's much larger bauxite production, however, annual aluminum output would average over two million tons.

An estimated 1,100 million metric tons of high-grade bauxite (50% Al 2 O 3 and 5% or less SiO 2 ) is present on the island of Jamaica. The bauxite overlies limestone of middle Eocene to lower Miocene age and accumulates in karst depressions and fault-controlled valleys.The principal parent material of bauxite is Miocene volcanic ash.
newly formed West Indies Federation. In 1962 when Federation was disbanded, the West India Regiment was also disbanded. Jamaica simultaneously sought her independence, which was achieved on August 6, 1962. With independence, Newcastle was given to the Jamaican government as part of a general settlement of all military lands in Jamaica.
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, while in hillside deposits this is aluminous goethite.

The Jamaican Government expects the value of mining exports from bauxite and alumina to improve to US$507 million ($77 billion), seven per cent higher than last year, with the pending reopening of the Jamalco plant but there's still concern over the other alumina assets.
Most of Jamaica's bauxite is refined into alumina. 4. Jamaica produces small quantities of aluminium. 5. Jamaica exports some bauxite unrefined. 6. Jamaica's output per worker is high compared to most other countries where bauxite is mined. 7. Wages in the Jamaican bauxite industry are low compared to other countries where bauxite is mined.
Abstract. 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, while in hillside deposits this is aluminous goethite. The difference in topographical setting between the catchment and hillside deposits ...
