Bauxite Mining - Uniprom

Uniprom's business model is to purchase bauxite ore from subcontractors who excavate the ore from the Uniprom-owned deposits, and then sell at pre-set contractural prices per extracted ton. These operations are the group's highest margin business and revenues continue to increase annually at double-digit pace.

Mining and Refining – Process

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.

Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)) and small amounts of anatase (TiO2) and ilmenite(FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-…
