mining net: CBG Bauxite (Aluminium Ore) Mining

OPEN PIT MINING While Sangardi was the orebody on which CBG's operations were founded, today between 85% and 90% of its output of raw bauxite comes from the Bidikoum and Silidara pits. After stripping any thin overburden, the ore is blasted and then loaded using hydraulic excavators into haul trucks for transport to the mine stockpiles.

1821 Bauxite discovered near Les Beaux in southern France by Pierre Berthier 1847 Armand Dufrnoy names the ore "beauxite" 1861 Henri Sainte-Claire Deville renames it as "bauxite" 1854 Sainte-Claire Deville discovers a method to separate kilogram amounts of

Typically, a bauxite resource contains 30-60% alumina (Al 2 O 3), and occurs as two main types: trihydrate ("low temperature") bauxite and monohydrate ("high temperature") bauxite The other main indicator of bauxite quality is the silica content, usually reactive silica for a low temperature bauxite or total silica for a high temperature bauxite

Cann Global Limited (previously Queensland Bauxite Ltd) has been focused on defining significant bauxite resources with a view to developing a bauxite mining and export operation that may include direct shipping ore (DSO). The Company has been focused on targeting long-life operations and positioning itself to participate in the growth of the bauxite sector.

Bauxite Ore As a convenient and common source of alumina, bauxite ore was first commercially mined in Jamaica in 1854. Almost 35 years later, Karl Joseph Bayer described the process (now known as the Bayer Process) that dramatically reduced the cost of aluminum metal production and moved it from the realm of precious metals into that of everyday commodity.

The first step in producing aluminium is mining this ore. Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the Caribbean, South America and Australia. Australia is the largest producer of bauxite, with five large mines supplying around 30 per cent of global production.

Optimal bauxite blends with constant composition secure optimal use of caustic soda and other reagents during refining and avoid costly processing of waste material. Control of the moisture content on the conveyor belt using near-infrared (NIR) technology, together with accurate monitoring of the composition of iron ore before shipment, guaranties constant ore quality to avoids penalties.
