In this approach, the optimality rule for feature selection is independent of the classifier, which will be used in the classifier design stage. For each combination we should use one of the separability criteria introduced previously (e.g., Bhattacharrya distance, J2) and select the best feature vector combination.

Aluminium hydroxide, or alumina tri hydrate obtained in the Bayer process, is calcined at temperature above 1200°C and up to 1600°C to manufacture special grade alumina. During calcinations, alumina hydrate crystals lose bound moisture and recrystallise to form alumina crystals. The particle size of alumina remains at 85-100 micron.

Alumina hydrate. Derived from bauxite, a natural aluminium-bearing mineral ore, in which the aluminium occurs as hydrated oxides. Comes in the form of white (light coloured), moist and fine powder which is odourless. Insoluble in water and organic liquids. Soluble in mineral acids (inorganic acids) and caustic soda.
