	Dealing with Red Mud - By - Product of the Bayer Process for Refining Aluminium
		The alumina process used today is essentially the one invented by Karl Bayer in 1887.
		They found that if the salinity of the sea water can be raised to about 1.5 times the ocean average, then the process is more efficient, requiring only 3.5 litres per 1,000 litres of red mud, as opposed to 6 litres of average salinity sea water.
		For example, if the residue is left in a tailings dam after the completion of treatment, the metal concentrations in the water will continue to decrease for at least 12 months.

	Aluminium
		To sustain the electrolytic process, alumina is fed into the pots at regular intervals to maintain a sufficient quantity of dissolved alumina in the bath.
		The process is controlled by a computer that detects and interprets minute changes in electrical resistance and determines when to feed alumina to the pot.
		The process of producing pure alumina from bauxite has changed very little since the first plant was opened in 1893.

		Sainte-Claire Deville announced an improvement in the process in 1854, that is reduction of aluminum chloride by sodium.
		Alumina (aluminum oxide) powder, fed to the electrolytic process, is produced by the Bayer process from bauxite ore. Bauxites contain 40-60% alumina, combined with silica (silicon oxide), iron oxide, and titanium dioxide.
		In the Bayer process, the alumina is dissolved in hot sodium hydroxide solution and the iron oxide and other oxides are removed as insoluble "red mud." Aluminum hydroxide is precipitated from the clarified solution by cooling and seeding with aluminum hydroxide crystals.
