Approaches to the Processing of Jamaican Bauxite

Abstract. Jamaican bauxite deposits can broadly be classified into two types, catchment and hillside, depending on their form and topographic setting. The major iron phase in catchment deposits is hematite, while in hillside deposits this is aluminous goethite. The difference in topographical setting between the catchment and hillside deposits has ...

2006-4-10  The Chemistry and Processing of Jamaican Bauxite. The first commercial extraction of alumina (Al2O3) from bauxite has been attributed toHenri Sainte-Claire Deville in about 1854. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the BayerProcess, which led to a dramatic reduction in the cost of aluminum metal.
