Bauxite Mining

Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminum-enriched soils are the result of the decomposition and lateritic weathering of …

Bauxite

Bauxite. Bauxite is an aluminum-rich sedimentary rock. It is the principal ore of aluminum. Aluminum in bauxite is hosted by aluminum hydroxide minerals, mostly gibbsite 4. The major impurities are iron oxides and hydroxides (which give reddish color to most bauxites) and clay minerals. Bauxite is a weathering product of aluminum-bearing rocks ...

Metro Mining's Bauxite Hills Project, Cape York, Queensland

The project employs a shallow, free-dig mining of bauxite ore, with no drilling and blasting required. The initial mining areas were pre-stripped, where topsoil and vegetation were removed by clear and grub activities, following which front-end loaders mined the bauxite ore. The ore was screened to a size of 100m prior to haulage.
