  • The Process of Mining Bauxite Dajcor

    The Process of Mining Bauxite by Dajcor Aluminum 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 mining Before mining can commence the land needs to be clearedBefore 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 revegetation of the site Next theMining and Refining – Process World AluminiumMining and Refining – Process The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer Two to three tonnes of bauxite are required to produce one tonne of alumina 90% of the global alumina supply of around 90 millionMining and Refining – Process World Aluminium
