The metal aluminium was first discovered and named by British scientist, Sir Humphrey Davy, in 1808. French chemist, Pierre Berthier while working near Les Baux in southern France in 1821, discovered soil with high quantities of aluminium oxide (or alumina) and named it bauxite after the village (Davis 1989; Gow and Lozej 1993).The …
However, there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding. Generally we choose crusher or grinding mill to crush the raw materials to be required fineness before used to produce aluminum. Bauxite crushing is relatively simple.

Aluminum industries use bauxite as the major raw material . Bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore, which is generally used for the production of aluminum appliances such as abrasives, ceramics, and refractories . The presence of impurities, including silica, iron oxides, and calcium contribute to the …
Bauxite ore is the main raw material used in alumina production. The alumina production in major regions of the world in 2017 is shown in Figure 1. It can be seen that the growth in aluminum production continues to be driven by countries in Asia and the Gulf area, 2017 global aluminum production is nearly 126 million tons, and China has ...
Bauxite Processing Plant. Preparatory stage: Crushing and grinding the ore blocks with a size of several meters into ore particles with a size of several millimeters. In this process, you need to use many …
Bauxite is the basic raw material that is refined into alumina, which in turn is sent to smelters for processing into aluminium. First discovered near Les Beaux in the South of France in 1821, bauxite was initially called "beauxite". In 1886, Charles Martin Hall and Paul Héroult independently developed a process for making aluminium from ...
