Calcined bauxite
Description
Calcined Bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures of 1600℃-1800℃. 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.
