Production – Red Mud Project

 · Production. Red Mud is produced during the Bayer Process. With this process, we can extract the aluminum (oxy)hydroxides from bauxites and get alumina, which eventually can be smelted and give aluminum. In 1888, Karl Josef Bayer developed and patented a process, which has become the cornerstone of the aluminium production industry worldwide.

2 The fine white alumina powder (Al 2 O 3) is transported by ship to NZAS from the alumina refineries. Four tonnes of bauxite produce two tonnes of alumina, which produces one tonne of aluminium. 3 The electrical current required for the smelting process flows in the reduction cell through carbon blocks

Abstract: South32 Worsley Alumina Pty Ltd operates several bauxite residue storage facilities at their refinery in Western Australia. The bauxite residue slurry is thickened and pumped onto the storage facilities which are constructed on an upstream basis using compacted earthfill embankments.

BAYER PROCESS BAYER PROCESS

BAYER PROCESS

BAYER PROCESS Bayer process is the process of refining alumina. from bauxite (aluminum ore containing 3050% of hydrated aluminum oxide) by selective extraction of pure aluminum oxide dissolved in sodium hydroxide. Prior to the Bayer process bauxite is crushed and ground in mills to fine particles (max. size "/).

Exhibit 6 presents a flow diagram of the Pidgeon process. In the Magnetherm process, suf ficient alumina is added to melt the dicalcium silie slag that forms at around 1500o C. This permits the reactor to be heated by the electrical resistance of the slag and further allows the reaction products to be removed in the molten state.
