Bauxite is the ore from which Aluminum is derived. The Bauxite must be ground into a fine powder before it can be further processed into Aluminum oxide and then smelted into Aluminum metal. A Bauxite grinding mill does the job.
Conditions within the digester (caustic concentration, temperature, and pressure) are set according to the properties of the bauxite ore. If bauxite ores have high gibbsite content, it needs to be processed at 140°C. The other type of bauxite ore- böhmitic bauxites require temperatures between 200 and 280°C.

BAUXITE AND ALUMINA. 1 (Data in thousand metric dry tons unless otherwise noted) Domestic Production and Use: In 2020, the reported quantity of bauxite consumed was estimated to be 4 million tons, slightly more than that reported in 2019, with an estimated value of about $110 million. About 79% of the bauxite
10%Bauxite is a rock type that is used to produce metallurgical-grade alumina and chemical-grade alumina/aluminum hydroxide using the Bayer process [ 8 ]. During this process, the finely ground bauxite ore is digested under pressure in a strong caustic (sodium hydroxide) solution at temperatures ranging from 100 to 260 °C.
The ore washing method of a kind of bauxite of the present invention, the size that it is characterized in that the ore mill milling medium of described selectivity size …
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.

Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

Bauxite processing is relatively simple and hand dressing is used commonly. The design is that: washing for three times, crushing for two times and hand dressing for one time. Along with the development of refractory material and alumina industry in our country, the production of bauxite raw materials is put forward higher and higher demand.
Generally speaking bauxite is found between 1 to 5 metres in depth and is shown in the image adjacent.Bauxite ore ranges in character from solid hard cap or duricrust, to friable fragmental or nodular material, to unconsolidated finely nodular pisilotic gravel. The bauxite gravel is typically composed of rounded light brown to red brown nodules.
