Guinea: Bauxite mining with surface miners maximizes profitability. West African Guinea is known for possessing the largest reserves of high-quality bauxite in the world. This potential has prompted the country to continually expand its bauxite mining sector in recent years, making substantial investments.
At this time, drilling and blasting was the main bauxite mining technique in use. Since then, however, the process has shifted to the more economical, safe and environmentally-friendly surface mining, and today Wirtgen surface miners extract of the ore.
Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin.
Drill and blast was the main bauxite mining technique in use at that time. "Since then, however, the process has shifted to the more economical, safe and environmentally friendly surface mining, and today Wirtgen surface miners extract of the ore," Wirtgen said, adding that 25 of its machines are currently in operation in the country.

Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation.
The most important barrier to remediation, use and long term sustainability of bauxite residue management is its high alkalinity. Bauxite residues and the runoff from storage areas can be treated to reduce their pH, further reducing the risk of environmental impacts and facilitating rehabilitation of the disposal area after closure.
Jan 29, 2014· Formed in a similar manner to iron laterites, bauxite is created by weathering of suitable rocks in a tropical climate. Typically deposits are large and at the surface. Mining usually involves simple strip-mining, without the need for open pit development. Lateritic bauxite formation
research revealed that mining activities, particularly bauxite surface mining which is ongoing in Sangarédi, was a major source of surface and table water depletion and pollution. They however noted that, the occurrence of flooding was also caused by bauxite mining. It has been noted that, water pollution has increased the risk of using
