The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina

Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

Aluminum sulfate can be made by reacting crushed bauxite ore with sulfuric acid, according to the following equation: Al 2 O 3 + H 2 SO 4 = Al 2 (SO 4) 3 + H 2 O. The bauxite ore contains 55.4% by weight of aluminium oxide, the remainder being impurities. The sulfuric acid solution contains 77.7% pure sulfuric acid, the remainder being water.

The crushed ore is mixed with the process liquor containing caustic soda and processed in a grinding mill to produce a slurry containing 35?0% solids. Sodium hydroxide is the main chemical used in the process to extract aluminum hydrate from bauxite.

The process stages are: 1. Milling. The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2.

Treatment of the run-of-mine bauxite consists mainly of crushing and drying before shipment. Ore wagons are tipped individually, the material being crushed to ?00mm before stockpiling. After reclaim using bucket-wheel stacker-reclaimers, the ore is dried from an average of 12.5% moisture to 6.7% for shipping.

Bauxite Crushing Plant. Bauxite ore is a kind of mineral which is often collectively formed by gibbsite, a boehmite or a diasporeone. Bauxite can be widely used in many industries, among which the most important is to be used to refining aluminum, working as refractory and abrasive materials, and raw materials for high alumina cement.
