Bauxite. Lead – Zinc. Rock phosphate. Metal slag. Coal. There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution.
ABSTRACT Bauxite ore is the primary mineral resource for the production of aluminum metal and includes gibbsite [Al(OH) 3], diaspore [α-AlO(OH)] and boehmite [γ-AlO(OH)]. Gangue minerals generally include iron oxides (Hematite [Fe 2O 3], Goethite [FeO(OH)]), silicates (quartz [SiO 2]), kaolinite [Al 2Si 2O 5(OH) 4] and others such as rutile/anatase [TiO 2].

The recently patented bauxite-based defluoridation method proposes the use of mildly processed (powdered) bauxite ore as a single-use dispersive batch media in a community-scale system [24]. Bauxite, a globally abundant ore of aluminum, is a viable, effective, and low-cost fluoride adsorbent alternative to AA.
Bauxite is a high-aluminum-content rock. That is the main ore that aluminium is mined from. One of the most common elements on earth is bauxite. It contains almost 25 percent-30% alumina. In the belt around the equator, bauxite is commonly found. The primary aluminium bearing ore with an aluminium content of more than 35 to 40 percent is bauxite.

Bauxite ore is soft and red clay, rich in alumina, and its name originates from Les Baux de Provence, It was a French geologist Pierre Berthier who first discovered bauxite near a village southern France in 1821. Later, a French chemist named Henri Sainte-Claire Deville officially termed the substance as "bauxite" in 1861.

The natural source of aluminum is bauxite ore. Bauxite is a mixed hydroxide of aluminum, silicium, iron, titanium and other metals. Bauxite is firstly transformed in alumina (pure aluminum oxide, Al 2 O 3) via caustic soda treatment and separation from other metals, and subsequent precipitation and calcinations. Then molten aluminum is obtained ...
bauxite from mine to alumina refinery over long distances are by rail or conveyor. Bauxite is delivered to the refinery relatively dry as run of mine ore ready for feed into the plant crushing/ grinding circuit. However, an alternative means of transport gaining attention is to prepare a slurry from the bauxite ore at the mine and pump it through a
The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite. A thick bed of kaolinite, goethite and some gibbsite underlies the bauxite.
