Bauxite crusher

Bauxite is a rock composed mainly of aluminum oxide and aluminum hydroxide minerals. These might include: gibbsite, boehmite and diaspore. The rock usually includes other materials such as iron hydroxides, clay, silt and free silica. It most often occurs as a residual soil material in tropical and subtropical areas. It is the primary source of aluminum. Aluminum comes from Canada, China, Australia, Nigeria, Brazil, Guinea, Jamaica and Russia.

The use of bauxite
Bauxite is the most common ore of aluminum. It is also used as an abrasive, however, this use is now being replaced by synthetic materials. Bauxite can be used in other industries such as cement, chemical, metallurgical, refractory.

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade or can be improved by a relatively simple and inexpensive process of removing clay. In many bauxites, clay is removed by some combination of washing, wet screening and cycloning, even by hand picking or sorting.

Bauxite mining Nigeria

Open pit mining is used to get bauxite. The water in bauxite is taken out of the ore. This leaves a white powder that is called alumina which is another name for aluminum oxide. Alumina is made into aluminum.

Eighty percent of world bauxite production, mainly from large blanket type deposits is from surface mines, with the rest, mainly from Southern Europe and Hungary, from underground excavations. On some surface deposits there is no overburden, and on others, the bauxite may be covered by 70 metres or more of rock and clay. Deposits that are hardened may require blasting in order to release the ore. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks or railroad cars and transported to crushing or washing plants or to stockpiles. Underground bauxite mines are used to exploit pockets or beds of deposit between layers of carbonic rock. Water in flow is a problem in most underground operations and dewatering shafts are often drilled before mining begins.
