Ore Deposits

This means a Y min of 0 will generate the ore above the mantle and a Y max of 1 will generate the ore below the level of the global ocean height. Sea level in the world can be determined by the Y of the surface of a big lake or by multiplying the height of the world by 0.43078 and rounding down.

Bauxite & Aluminum

The bauxite deposits show no internal structural characteristics and their colour is mainly a uniform dark red with localized variations from off-white to yellow, depending on the iron content. Thickness of the bauxite cover is extremely variable, ranging from a few feet to an average of about 30 feet, up to as much as 100 feet.

ARTICLE: Addressing the Challenge of Bauxite Residue

Bauxite ore contains 30-60% aluminum oxide (Al 2 O 3). In the Bayer process (Figure 2), the bauxite is digested in a pressure vessel along with a sodium hydroxide solution (caustic soda) at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.

Bauxite Mining and Alumina Refining

The bauxite ore contains aluminum trihydrate (Al(OH) 3). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3: The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then ...

Assume that all of the bauxite ore mined from the ground is pure Al2O3.

Bauxite

Bauxite deposits form close to the surface. Hence, all the mines in the world are open pit. About 8-14 tons of bauxite is needed to produce one ton of aluminum 1. So the ore of aluminum needs to be fairly rich in this metal to be worth mining. Aluminum is extracted solely from bauxite, but that does not mean that there are no alternatives.
