Handling of bauxite - Loading, discharging environmental impacts Bauxite is one of the world’s most abundant minerals and is strip-mined in many places. Nearly all is processed into alumina for aluminium production. Bauxite contains iron-bearing clay or red mud, which often leaves stains on the hold paint that can prove difficult to remove.

The chemical and physical properties of bauxite residues are determined by the nature of the bauxite and the effect of the Bayer process. The technology and operating procedures at individual refineries will impact the water content and pH value of the material being discharged - two key factors in bauxite residue management.

GBWG indicated that Bauxite Fines containing more than 30% of fine particles less than 1 mm; and more than 40% of particles less than 2.5 mm (Group A) may be unstable because of moisture content, resulting in dynamic separation and formation of a liquid slurry (water and fine solids) above the solid material, and a free surface effect which may affect the ship's stability.

Jul 13, 2016 The procedures used for bauxite resource estimation are summarised using examples from Australia, Africa, South America and Asia. In the all studied cases the bauxite resources were estimated by drilling and sampling drill holes at 0.25–0.5 m intervals. Short sampling intervals are necessary for accurate estimation of the mineralisation contacts.
