Sustainable Bauxite Mining Guidelines
Bauxite mine operators should assess the social, environmental and economic impacts of their activities before commencement of mining. Such anassessment includes identifying affected stakeholders , the potential impacts of the planned mine and those measures which should be applied to prevent and limit negative and maximise positive outcomes.
Mining and Refining Process
Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.

represent for resident community. In addition, mining companies still used methods that have been bound like blasting used by SMB (Boke mining company) in Katougouma mine, deep drilling mine used by CBG (Guineas bauxite company); which is seriously affecting Sangaredi rivers and water table. Those techniques have huge direct
Bauxite
Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.
Mining and Refining Process World Aluminium
The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina
Bauxite tailings
Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).
