Mining and Refining Bauxite Residue Management

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.

Mining and Refining Bauxite Residue Management

It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (10 30%), titanium dioxide (2 15%), silicon oxide (5 20%) and undissolved alumina (0 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source.

Bauxite mininig in Guinea PR Wirtgen

The most commonly used models for bauxite mining in Guinea are the 2200 SM and the 2500 SM. The first is compact yet powerful, with a 2.2 m-long cutting drum and 708 kW of engine power. It is able to cut rock with unconfined compressive strengths of up to 50 MPa, ideal for medium-sized mining operations.
