The bauxite ore is first crushed and ground into fine particles which are then combined in autoclaves with a caustic soda solution. Aluminum oxide dissolves while impurities within the ore remain in a solid state in the autoclaves, which function at temperatures in the range of 200 to 240 ºC and at pressures of up to 30 bar.

Our bauxite has a silica content of less than 2% and a small particle size. This means the process for crushing and grinding is not as intensive. The small particle size and low silica content make our Bauxite one of the highest in value worldwide. Refineries that purchase out bauxite can extract high-quality aluminum from Jamaica''s bauxite.

harder particles. SAG mills treating bauxite are often operated like ball mills, mainly on account of the soft nature of the bauxite and size of the crushed feed (< 10 cm). The actual sizes and number of mills used to deliver a selected particle size can be estimated using conventional bond ball calculators and JKSimMet modelling.
