Normallybauxite contains from 30% to 60% Aluminum oxide (which is called also alumina)and it is easy to be found near the earth's surface. The process can be dividedinto two parts; the extraction of alumina from bauxite, and the smelting ofAluminum metal from alumina. Separation of alumina generally is done by theBayer Process.

Apr 12, 2022However, the data obtained in the current study showed that the increased speed of agitation from 150 to 300 rpm led to a decreased biomass from 19.4 to 14.7 mg/L in test 5 at 8% pulp density. In addition, a higher agitation speed did not give the expected higher biomass, though a slight increase in leaching amounts of Ti was presented (Fig. 3 ).
