ENVIRONMENTAL ASPECTS OF BAUXITE, ALUMINA AND

In alumina production, the disposal of bauxite residue saturated with caustic soda ("red mud") is the main problem, although emissions to the atmosphere of gases and particles from boilers, calcination furnaces and bauxite dryers may also be important. Worldwide, the most common method of disposal of

The Chlorination of Alumina and Bauxite with Chlorine and

The kinetics of chlorination of alumina and bauxite with CO/CI2 mixtures were studied in the range 300-1100°C. The temperature of prior calcination is critical in determining the reaction rates. An optimum chlorination temperature in the range 600°C-750°C was demonstrated such that there is no increase in reaction rates with increasing temperature.

Australian Researchers Assess the Commercial Viability of

Aug 03, 2020· Commercializing alumina refining using solar heat Approximately 27% of Australia’s industrial carbon emissions come from alumina refineries, in which fossil fuels are burned to heat the processes. But concentrated solar thermal (CST) could provide up to half of the heat needed. Australian researchers have for the first time demonstrated a novel solar reactor for calcining []
