Soil pollution and toxicity in an area affected by ...

Apr 15, 2019  1. Introduction. Bauxite manufacturing by the Bayer process in alumina production is associated with a by-product, bauxite residue (BR), traditionally termed “red mud” (Xue et al., 2016, Xu et al., 2018).In turn, BR has raised environmental concern in areas affected by plant effluents as related to its recognized toxicity since early studies (Trieff et al., 1995, His et al., 1996, Dauvin ...

The emissions generated by CBG operations stem from its industrial process as well as the use of heavy machinery and vehicles in Kamsar, in the mining area and along the rail line linking Kamsar to Sangarédi. Most of the emissions are generated at the Kamsar plant from CBG’s use of fossil fuel (fuel oil) to generate power and to dry bauxite.

Mining and Refining – Energy Efficiency

Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.
