In the first segment of our investigation that can be read here, we observed that none of the bauxite-producing countries in Africa own both a bauxite refinery and a smelter plant. The different leading bauxite producing countries, either sell the raw bauxite, transform it into alumina and sell alumina, or have to import the alumina to […]
We can get aluminum from bauxite beneficiation process, and the elements of residues in the process are iron oxide (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%), and insoluble oxidation aluminum (0-20%).. These elements are difficult to completely eradicate from the residue, so it has caused a series of ecological problems.
