Nanofiltration of Bayer process solutions

Journal of Membrane Science, 2006
Abstract The Bayer process is used for refining bauxite into smelting grade alumina (Al2O3), which is the precursor of aluminium. The process was developed and patented by Karl Josef Bayer 110 years ago and has become the cornerstone of the aluminium production industry worldwide.

Vanadium Recovery from Bayer Process Liquor Residue

JOM, 2023
The objective of this work is to develop a vanadium recovery process from a liquor residue of Bayer process. Vanadium finds application in strategic industrial sectors such as steel production and energy storage. The recognized importance of vanadium has pushed academic and industrial research towards the development of technologies for its recovery ...

Thermodynamic simulation of the Bayer process

International Journal of Materials Research, 2008
Abstract The Gibbs energy minimiser incorporated in the thermodynamic subroutine library ChemApp and a thermodynamically consistent, ten-component Bayer liquor model were applied to a simulation of the Bayer process employed worldwide for the refining of alumina from bauxite ores. As well as the liquor cycle from digestion, clarification,

Recovering gallium from residual bayer process liquor

JOM, 1991
Gallium is normally obtained by direct electrolysis as a by-product from Bayer process residual liquor at an aluminum processing plant. However, to permit any net accumulation of the metal, the gallium concentration must be at least about 0.3 g/l in the liquor.

Insoluble Organic Compounds in the Bayer Process

Industrial & Engineering Chemistry Research, 2001
During the dissolution of bauxite in a high-temperature (250−255 °C) Bayer process, which separates aluminum hydroxide and oxide in the ore from iron oxide and other impurities, a number of insolub...

Basic Principles of Bayer Process Design

2016
Data used in Bayer process design are presented, with an account of the methods used in evaluation of bauxites as a source of alumina, and of plant design, with particular reference made to extraction, silica, mud separation, decomposition, causticization, flow of fluids, and heat transfer.
