methods of mining bauxite

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 site.

method of bauxite mining

the bauxite mining and alumina refining process bauxite mining bauxite deposits are alumina rich laterite deposits that result from the weathering of parent rocks. the deposits are generally relatively shallow (less than 10 metres) and are mined by open cut methods. apart from the aluminium minerals, from which alumina is extracted, bauxite is predominantly made up of iron and silica minerals.

Bauxite in Jamaica Geo for CXC

Bauxite is the ore from which aluminium is made. Jamaica contains some of the largest known deposits of bauxite in the world. The mining areas are located in the western and central parts of the island. After mining, most of the bauxite is carried to alumina plants where it is refined into alumina. The alumina (or in some cases unrefined bauxite) is carried to export ports by rail. Most of Jamaica’s bauxite is refined
