Mining and Refining – Process
Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. 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 application of multiple-point statistics (MPS) in the mining industry is not yet widespread and there are very few applications so far. In this paper, we focus on the problem of algorithmic input parameter selection, which is required to perform MPS simulations. The usual approach for selecting the parameters is to conduct a manual sensitivity analysis by testing a set of parameters and

Bauxite residue (red mud) is a hazardous waste generated from alumina refining industries. Unless managed properly, red mud poses significant risks to the local environment due to its extreme alkalinity and its potential impacts on surface and ground water quality.

The race for bauxite – China’s depleting resources add fuel
More than 90% of the world’s bauxite reserves, called laterite bauxites (derived from alumo-silicates), are concentrated in tropical and subtropical regions from approximately 60 million years ago. Large deposits are found in Australia, South-East Asia, South America and India. They are located beneath the surface and are extracted through the open pit mining method. In the Caribbean, as

Bauxite
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

Bauxite
However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability. These deposits usually have a beneficiation plant that washes the bauxite and sends the high silica fines (kaolinite and/or quartz) to a tailings dam prior to ship loading the bauxite.

Bauxite Mining
Open-pit panel mining has been the normal surface method since the early 1960s. A strip or block of bauxite is exposed and mined, and then another panel is exposed. The first panel is normally refilled with waste rock. Several panels typically were open at the same time to supply the proper blend of ores to meet mill specifications. Beginning in the early 1990s, major reclamation programs were
