Waste management is extremely important for sustainable and hazard free mining and refining of bauxite. Malvern Panalytical solutions support the frequent monitoring of particle size, mineralogy of an elemental composition of red mud to promote its settling and filtering properties and the optimal consumption of coagulants and flocculants.

Production of MicronSized Particles of Bauxite by

A novel process involving the production of micronsized particles of bauxite by circulating pulverization experiment is proposed. This method is through highpressure gas infiltration, uniform and equal stress loading, and overcoming tensile strength between particles, which is different from the traditional ball milling based on overcoming

PAPER OPEN ACCESS A study of bauxite tailing quality

The bauxite that has particle size 2+1 mm also can be processed to the Bayer process as the alumina content for this fraction is about 40%. The washed bauxite tailings that have particle 2+1 mm fraction, while the latter was further milled using ball mill to obtain a fraction of 140+270 mesh (0.105+0.053 mm) and 270 mesh (0.053 mm).

FeSi alloys production and alumina extraction from coal

In order to clarify the relationship between the magnetic separation efficiency and the particle size distribution of the Fe Si alloys, a statistical analysis was performed by employing the optical microscope and Imagepro J software. Fig. 11 (d) shows the particle size distribution of the Fe Si alloys as the Fe/Si ratio ranged from 1.0 to 2.0
