Handling of bauxite Loading, discharging & environmental

An increasing concern is the loss of habitat for Jamaica's unique plant and animal species. Also, bauxite mining severely affects the water retention capability of the soil. The Jamaican Mining Act of 1947 requires mines to remove topsoil before mining, and restore it as part of the reclamation process.

ENVIRONMENTAL ASPECTS OF BAUXITE, ALUMINA AND

The main environmental problems associated with bauxite mining are related to the rehabilitation of mined-out areas and the disposal of tailings. Emissions of dust consisting of clay and bauxite particles from dryers’ chimneys can also pose problems.

Sustainable Bauxite Mining Guidelines

18/05/2018· The large footpr int of (predominantly open cut) bauxite mines and the fact that they are commonly found in tropical and sub-tropical areas mean that deposits often overlap, or are adjacent to, areas of high conservation value. Effective mitigation of biodiversity impacts is critical to achieving sustainable outcomes.
