The Process of Mining Bauxite Dajcor
27/02/2019 The Process of Mining Bauxite : The Process of Mining Bauxite Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant It is found in a belt around the equator and is generally extracted by opencast miningBauxite 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 postmining Mining and Refining – Process World AluminiumBauxite Mining Scrapers and small excavators are used to remove the remaining overburden and expose the caprock Depending on the depth of the caprock, it can be broken by blasting, or simply removed with scrapers and excavators The bauxite is then mined using excavators or loaders to load the bauxite onto haul trucks and transported to the crusher Bauxite Mining The Australian Aluminium Council
