The Bauxite-Alumina Industry has been a powerful actor
Bauxite ore contains alumina, iron oxides, organic matter, water, and a host of minor constituents. The Bayer process involves firstly grinding of the dry ore in a ball mill in which it is mixed with a certain amount of lime. The lime is obtained by heating limestone in a kiln. To dissolve the alumina out of the bauxite/lime mixture,

12.1 Primary Aluminum Production
2020-11-2 Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.
