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.

Noranda Bauxite, partnered with the Government of Jamaica and New Day Aluminum, is located on the North Coast of Jamaica. Here, we dry and ship more than 5 million dry metric tons of bauxite per year, and we have been for over 60 years. Because of Jamaica’s low-silica high-quality bauxite, it is well suited for global alumina and cement
Strahl E.O., “The mineralogy of Jamaican bauxite and its effect on Bayer process technology”, Journal of the Geological Society of Jamaica: Bauxite/Alumina Symposium,
The gibbsite content of Jamaican bauxite ranges from 34-46%, whereas boehmite can range from 1-12%. For this reason, Jamaican bauxite may be classified as `mixed’ trihydrate/monohydrate or gibbsite/boehmite bauxite. Some amount of blending can be tolerated in the processing, and this is encouraged in order to maximize use of the resource.
Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010,approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis. Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory. Usually, bauxite ore is heated in a pressure vessel along with a sodium hydroxide

Jamaica Jamaica Economy: Jamaica’s economy is mixed but increasingly based on services, notably tourism and finance. Since independence in 1962, the country has developed markedly but unevenly. Mining and manufacturing became more important to the economy in the latter part of the 20th century, while the export of agricultural commodities declined.
