Calcination's wiki: Authorities differ on the meaning of calcination (also referred to as calcining ). The IUPAC defines it as 'heating to high temperatures in air or oxygen'. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.

During the Bayer process for alumina production, the molecular formula of the bauxite residue is approximately equivalent to Na 2 O·Al 2 O 3 · 2 ·nH 2 O. This means that 1 kg of SiO 2 in bauxite will produce 1 kg of Al 2 O 3 and kg of Na 2 O in bauxite residue. Thus, the extraction efficiency of alumina is low when processing lowgrade bauxite.

Pour la calcination des minerais de phosphates, les productions sont plus importantes et peuvent atteindre 6 000 t/j. La calcination sert à éliminer la matière organique ou la gangue carbonatée. On rencontre les fours rotatifs, des fours à lit fluidisé, ou à calcination éclair ou flash (selon un principe proche de la fusion flash).
