bauxite processing in jamaica and guyana 27. Francis (1982) maintains in his input-output study: "Testing of the model in relation to the stability of the input-output coefficients is a feasible exercise but one which is fraught with difficulties" (p. 301).
The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue....Chat Now

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. The Kirkvine works were completed around 1952 and the first shipment of alumina was consigned to a Norwegian smelter in January 1953.
Processing of Bauxite Ores. To Obtain Aluminum. Bauxite, the primary aluminum ore, uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite....Chat Now
