The Process of Mining Bauxite Dajcor

27/02/2019· 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 cleared of timber and vegetation

Mining and Refining – Process World Aluminium

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting
