Arsenic-bearing minerals commonly occur within ore bodies that contain lead, nickel, gold and most notably copper. Due to similarities in the surface properties of base metal sulfide minerals and arsenic-bearing minerals, selective separations of ars

Sodium oxalate is an organic impurity produced during the Bayer refining of bauxite as a result of the degradation of humic materials associated with the ore. Physico-chemical oxalate destruction techniques, such as combustion, are often expensive an

The kinetics of iron and sulfur oxidation by selected bioleaching strains grown in simple chemically defined media have in some instances been studied exhaustively. However, there is very little available information on the growth and leaching kineti

Western Australian bauxite deposits are naturally associated with high amounts of humic and fulvic materials that co-digest during Bayer processing. Sodium oxalate remains soluble and can co-precipitate with aluminium hydroxide unless it is removed.
