The Chemistry and Processing of Jamaican Bauxite

2014-6-13 The Chemistry and Processing of Jamaican Bauxite. The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process

Leaching Kinetics of Bauxite in Hydrochloric Acid:

2018-6-9 The Bayer process is currently used to produce cell-grade alumina from bauxite. However, if the reactive silica content in the bauxite exceeds 7%, losses of caustic and aluminium as sodalite (2 Na 2 0.2 Al 2 O 3 ·3 SiO 2 ·2 H 2 O) become economically unacceptable. As Australia possesses large tonnages of bauxite containing more than 7% reactive silica, a process

The mineralogy of bauxite for producing smelter

Aluminum-producing companies rely on low-cost, high-purity, smelter-grade alumina (aluminum oxide), and alumina production utilizes the bulk of bauxites mined world-wide. The mineralogy of the bauxites has a significant impact on the operation of the Bayer process for alumina production. Typically, the Bayer process produces smelter-grade alumina of 99.5% Al2O3, starting from bauxite
