The local Mining and Quarrying sector is mainly driven by bauxite and alumina, which generate the most revenue for the sector. However, the sector has become more diversified over the years with the emergence of non-metallic minerals such as limestone, silica sand, marble, marl and fill, and clay.
List of countries by bauxite production - Wikipedia. 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 ... 6 Indonesia 11000.
Because of Jamaica's low-silica high-quality bauxite, it is well suited for global alumina and cement industries. Aluminum production starts with the strip mining of the raw material bauxite, which is a clay-like soil found near the equator.

Jamaica's bauxite industry rose to become a global leading bauxite producer, just five years after the first bauxite shipment left the island in 1952 (Jamaica Bauxite Institute).

The Jamaica Bauxite Mining Company (JBM) was set up to hold the assets acquired from entering into partnerships or joint ventures with the companies, and the Bauxite and Alumina Trading Company (BATCO) was established to carry out commercial (trading) activities on behalf of JBM.
Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Rapid degradation of disturbed soil from a karst bauxite mine in Jamaica was recorded. Substantial macronutrient losses were incurred during a short (1 month) or a long (12 months) storage of the replaced topsoils during frequent wet/dry changes. The results suggested very high rates (>70% in the first year) of soil degradation from storage, alongside moderate rates (30%) within the same ...
