Extraction Process of Aluminium from Bauxite Ore
Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum. It contains varying amounts of
Nickel: smelting, producing-Metalpedia
Nickel: smelting Extraction and purifiion Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel appliions, 75% pure nickel can be used without further purifiion, depending on the composition of the impurities.
