Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Bauxite is the main commercial mineral from which aluminium oxide is extracted, which in turn is smelted to form aluminium metal. Typically, a bauxite resource contains 30-60% alumina (Al 2 O 3 ), and occurs as two main types: trihydrate ("low temperature") bauxite and monohydrate ("high temperature") bauxite. The other main indicator ...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 nepheline syenite, an intrusive …
