Bauxite in Jamaica occurs primarily in the parishes of St. Elizabeth, Manchester, Clarendon, St. Ann and St. Catherine. Approximately thirteen million tonnes are mined each year. As part of its mandate, the JBI manages the use of bauxite land in both the pre-mining and post-mining stage and together with the Commissioner of Mines ensures

Bauxite mining Bauxite is mined by opencast methods using the most modern large scale earth-moving equipment. The present emphasis is on blending to produce a uniform grade ore, the use of lower grade bauxite, and the maximisation of reserves. Mining is most commonly carried out using a benching method requiring power shovels and draglines.

Most of Jamaica's bauxite is red or reddish-brown, a peculiarity which indicates the occurrence of iron mineral in the ore. There is no overburden covering the bauxite, as is the case in many other countries. The ore lies on the surface and is relatively easy to mine. The mining laws of Jamaica require the mining

The first step in producing aluminium is mining this ore. Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the Caribbean, South America and Australia. Australia is the largest producer of bauxite, with five large mines supplying around 30 per cent of global production. Bauxite mining has five steps:

The bauxite formed a bed averaging 2 m thick. The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite.
