mining in jamaica
jamaica is recognised for its tourism and bauxite industries. jamaica is the world’s fourth largest bauxite producer, after australia,brazil and guinea.
there is considerable potential in parts of the industrial mineral sector. jamaica’s calcium carbonate resources include 152,000 mt of recoverable lisbmne, 350 mt of recoverable marble, and about 350 mt of high purity, high brightness ground calcium carbonate (gcc) or whiting appropriate for filler-grade material. sbm is now the second most important mineral exported from jamaica after bauxite.
as well as marble from st. catherine’s parish, jamaica has been producing salt, silica sand, and stone. some semi-precious stones like agates, jasper and carnelian are used in an indigenous jewellery industry while some mineral and spring water is being marketed abroad. clays (80% of which are naturally coloured red) are available to produce commercial quantities of ceramics and building components. the existing reserves are 250 mt including disordered kaolinite (near white to buff firing), red firing illite to montmorillonite and light firing clays. most of the island’s gypsum is in the bull bay area of eastern st. andrew and western st. thomas.

bauxite mining in jamaica
in 2003 jamaica produced 3.84 mt (8.2% of western production) of alumina with total bauxite production totalling 13.44 mt compared to 13.1 mt in 2002.the country has an estimated reserve base of 2.500 mt of bauxite (2003).
in may 2005 alcoa world alumina and chemicals (awac) and the government of jamaica approved plans to expand the jamalco alumina refinery in clarendon, jamaica by 150,000 metric tons per year (mtpy) as the first phase of the overall 1.5 million mtpy capacity expansion. this first phase will cost approximately $77 million, with the commitment of another $25 million to finalize detailed engineering on the full project over the next three months.
full production from the first phase is expected by the end of 2006. expansions at jamalco stem from a 2002 agreement with the jamaican government to remove a nearly 30-year-old levy on bauxite in order to encourage investment. jamalco is a 50/50 relationship between alcoa world alumina and chemicals (“awac”) – a global alliance between alcoa and alumina ltd. – and the government of jamaica, with awac as the managing partner.
in february 2002 kaiser aluminium one of the largest bauxite producers in jamaica filed for bankprucy. in april 2004 kaiser aluminum announced that russian aluminium (rusal) was the successful bidder at $295 million in an auction for kaiser’s 65 percent interest in alpart, a jamaican alumina and bauxite joint venture. kaiser completed the sale for a gross sales price of $315 million in july 2004.

bauxite mining equipment in jamaica
in jamaica bauxite mining industry, sbm can supply you bauxite crusher such as jaw crusher, cone crushers or gyratory crusher for crushing and bauxite grinder mills such as ball mill, vertical roller mill, raymond mills for grinding process in bauxite processing plants.
the average thickness of the bauxite is about 4m to 10m. an excavator or loader is used to load the bauxite onto haul trucks for transport to the first crusher. there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding.
however, there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding. generally we choose ciros crusher or grinding mill to crush the raw materials to be required fineness before used to produce aluminum. bauxite crushing is relatively simple. generally we use the professional sbm mining equipments for bauxite crushing.
