Jamaica is among the top six countries in the world in terms of bauxite reserves and our facility has been mining bauxite continuously for approximately 60 years. Jamaican bauxite is a high quality, low silica bauxite well suited for the global alumina and cement industries.
Bauxite quality is determined by its relative proportion of available Alumina (AI2O3) compared to Silica (A/S ratio). High quality bauxite is a key condition to optimize alumina production: a low-quality bauxite generates red muds and requires more raw material consumption.
After crushing and milling, the bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (NaOH) at a temperature of 150 to 200 °C to extract the aluminium as a sodium aluminate solution. Flow control of the NaOH solution at such elevated temperatures is crucial.
