The discovery of bauxite occurred near Les Baux, France, an ancient village near the Mediterranean Sea named for, and carved from, a rocky outcrop. On March 23, 1821, a geologist named Pierre Berthier discovered a reddish, clay-like material. He found that the substance, later named bauxite after the village, consisted of about 50 percent ...

Approximately 90 percent of all bauxite mined is refined into alumina, which is ultimately smelted into aluminum. The remaining 10 percent is used in other applications, such as abrasives, refractories, and proppants in the recovery of crude oil. Approximately four tons of high-grade bauxite yield two tons of alumina, from which one ton of ...

3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.

Bauxite is the world's principal source of aluminium and can vary from very soft earth to very hard rock. It can occur as red-yellow compacted earth (both friable and re-cemented), small red round pebbles (pisolites), or large pale (pink, white, buff) hard stones. Bauxite is a mixture of aluminium minerals, clay minerals, and insoluble materials.
