study from bauxite ore deposit

Bauxite Hills Pre-Feasibility Study - friendsofbest.org

Once the bauxite ore is exposed the FEL will mine the bauxite down to the transition material. It is a shallow deposit and pit slope parameters are to the natural angle of repose. The mined out pit will be back-filled by the overburden. A Pit Optimisation study was conducted in order to determine the economic mining limit of the ore

Bauxite - an overview | ScienceDirect Topics

Bauxite, the principal ore used for aluminum smelting, is named after Les Baux, Provence, the village where the first deposits were discovered. Bauxite contains hydrated alumina equivalent to as much as 40–60% Al 2 O 3, and is free of the other siliceous materials leached out over time. However it still contains 10–30% iron oxide, and some ...
