	The Chemistry and Processing of Jamaican Bauxite
		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 alumina plants were said to be working at 96% capacity for the first time in many years and for the first quarter (1997) produced 816,999 tonnes.
		Hall process for electrolytic reduction of alumina to aluminum is appropriately provided at Oberlin College, from where Charles Hall had graduated only eight months prior to his successful experiment.

	Alumina (Aluminium Oxide) - The Different Types of Commercially Available Grades
		Smelter or metallurgical grade alumina is the name given to alumina utilised in the manufacture of aluminium metal.
		Fused alumina is made in electric arc furnaces by passing a current between vertical carbon electrodes.
		High purity aluminas are normally classified as those with a purity of 99.99% and can be manufactured by routes starting from Bayer hydrate using successive activations and washings, or via a chloride to achieve the necessary degree of purity.

		Alpha alumina is composed of colorless hexagonal crystals with the properties given above; gamma alumina is composed of minute colorless cubic crystals with sp.
		Alumina is also used in ceramics, in pigments, and in the manufacture of chemicals.
		Hydrated alumina is used in mordant dyeing to make lake pigments; it is also used in glassmaking, in cosmetics, and in medicine as an antacid.

	Aluminium chemicals
		Alumina (aluminium oxide, or Al) is a white powder produced from bauxite ores (iron alumino silicate).
		Comalco is considering a 1 million tonne alumina operation for Gladstone, drawing on bauxite from Weipa deposits and using the alumina for its smelters at Boyne Island, Qld, Bell Bay Tasmania and at Tiwai Point, New Zealand.
		Hydrated alumina is available from Alcoa, cheap high quality silica is also available, and from the perspective of Coogee Chemicals as a manufacturer, it would use their sodium silicate, sodium aluminates, aluminium hydroxides and caustic soda.
