The concentration, temperature and pressure used depend on the source of the bauxite and exactly what form of aluminium oxide it contains. Temperatures are typically from 140°C to 240°C; pressures can be up to about 35 atmospheres.
The principal ore of aluminium, bauxite, usually contains SiO 2, iron oxides and titanium oxide (TiO 2) as impurities. Concentration is carried out by digesting the powdered ore with a concentrated solution of NaOH at 473 – 523 K and 35 – 36 bar pressure.

For China it is reported that bauxite ore with the ratio of aluminium and silica greater than 10 accounts for only 10% among all the bauxite in China, and the bauxite with the ratio of aluminium and silica between 7 and 10 accounts for only 20%, and between 4 and 7 accounts for 60%, and between and accounts for 10%.
Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.
Bauxite Ore Processing: Aluminum is found in varying amounts in nature as aluminosilicates (contains aluminum, silicon, and oxygen) in various types of clay. As the minerals are weathered they gradually breakdown into various forms of hydrated aluminum oxide, Al 2 O 2 O, known as bauxite.

As we go around the circuit, the aluminium concentration is decreased in the Precipitation (or crystallisation) step, and we end up with a "spent" liquor. This spent liquor (now poor in dissolved aluminium) completes the circuit to treat more bauxite. So the crux of the Bayer Process is dissolution of aluminium from its ore in the early part of
