Calcination refers to thermal treatment of a solid chemical compound (e.g. mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O 2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition.

Calcined Bauxite. Calcined Bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures. This process of calcining (heating) bauxite in kilns removes moisture and gives Calcined Bauxite its high alumina content and refractoriness, low iron, and grain hardness and toughness.

Calcination is the process of heating a solid material in order to cause chemical separation of its components. The diversity of chemical separation lends calcination to accomplishing a range of objectives, from the removal of chemically bound (crystalline) water, to the volatilization of contaminants from a source material, thermal decomposition, and even phase changes.
