Calcined bauxite is available "run of kiln" i.e. uncrushed or in fractions and as ball milled powder according to customers' requirements, in bulk or bagged. Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content.
