The Boke mine in Guinea, Africa, holds some of the world''s highestquality bauxite deposits. To efficiently extract, process and transport the material from the mine, located approximately 30 km from the northern shores of the Rio Nuñez in Boké Prefecture, the mining company, SMB (Société Minière de Boké) was formed in 2014.
However, bauxite ore from northern Brazil and Vietnam has a high clay content, and has to be washed before processing3. Underground deposits require underground mining to extract them economically. Figure 1: Typical processes involved in surface mining of bauxite deposits3 Bauxite ore is then refined into alumina (Al 2 O 3
Bauxite mining, which is considered as surface mining, is land extensive, noisy and dusty. Mining pits are often interspersed with small rural communities, thereby requiring companies relocate the people and/or to monetarily compensate them. An increasing concern is the loss of habitat for Jamaica''s unique plant and animal species.

Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminumenriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive igneous rock.
