Mining and Refining – Bauxite Residue Management

Initially, the residue is washed, to extract as much valuable caustic soda and dissolved alumina as possible. The caustic soda is recycled back into the digestion process, reducing production costs and in turn lowering the alkalinity of the residue. The pH level of the residue is generally up to 13 or higher in some cases, due.

Bauxite - Wikipedia

Lateritic bauxites (silicate bauxites) are distinguished from karst bauxite ores (carbonate bauxites). The carbonate bauxites occur predominantly in Europe, Guyana, and Jamaica above carbonate rocks (line and dolomite), where they were formed by lateritic weathering and residual accumulation of intercalated clay.

Bauxite: The principal ore of aluminum. - Geology

Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite. The aluminum is precipitated out of solution in the form of.

Bauxite Mining and Alumina Refining: Process Description and .

Most bauxite occurs close to the surface, with only 1 or 2 m of overburden. Typical deposits range in thickness from 3 to 15 m. The majority of the bauxite can be mined and processed without beneficiation (further treatment of the ore to concentrate the minerals), but the ore in the north of Brazil and in Vietnam has a high clay.
