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

It is a procedure very important before you remove aluminum from bauxite mine that is crushing and Bauxite mining equipment . Generally we choose crusher and mill to crush the contents first before necessary finesse used to produce aluminium.
Mill for grinding of bauxite is relatively simple. We use professional equipment of the bauxite of grinding for bauxite of grinding process. As the leading mill manufacturer, we have also closely followed the bauxite of crushing plants at home and abroad.
Saudi Arabia bauxite ore Crusher
The Bauxite Crusher contains primary crusher, secondary crushing, crushing fineness of sifting equipment, equipment to transfer, to supply equipment, washing equipment and so on. We can also provide portable crusher, mobile crusher for clients. These enrichment plants are necessary equipment for the project.
Bauxite crushing, washing, screening & grinding machine
Primary crushing: Jaw Crusher, play the role of crushing primary process;
Secondary crushing: Crusher impacts the role as coarse crushing process.
Tertiary crushing: Symons cone Crusher role than equipment fineness of grinding;
Food equipment: vibrating;
Screening: Vibrating screen;
Transportation equipment: band conveyor;
Equipment cleaning: machine wash sand;
Crusher: Moulin de bauxite Ball, Raymond mill, role-playing of the powder of Bauxite processing plant.
From there the ore is digested in a heated pool, tank pressurized at temperatures up to 450 ° F Defers and 500 psi pressure. Generally, there are different types of ore of alumina from bauxite deposit, and these require different temperatures to digest. The digester low temperature usually operates at 275-290 degrees f. sodium hydroxide is used to dissolve alumina in the digester. Pregnant liquor is separated from the residue of red mud with a series of thickeners implemented in agreement settling Backwashing, tenure washing liquor for alumina from residues, until the sterile residues remain. Contaminates various (iron, organic matter) may interfere with the process and may require the routines below to remove them.
Filtration, as drum vacuum or pressure filters, remove silica and low solids of liquor of alumina bearing clarified. The fluid containing dissolved alumina is pumped in tanks or reservoirs called precipitation crystallization. The liquid is cooled to decantation thickeners backwash water, and as it cools, alumina hydrate slowly precipitates from the tank, according to the formula.
