In the roasting process, sulfuric acid is formed and acts on the clay to form aluminium sulfate, a similar condition of affairs being produced during weathering. The mass is now systematically extracted with water, and a solution of aluminium sulfate of specific gravity 1.16 is prepared.
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder.The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today.
Anhydrous aluminum sulfate is a white crystalline solid. Aluminum sulfate is also obtained as an 18- hydrate Al2 (SO4)3.18H2O. Both forms are soluble in water, noncombustible, and nontoxic. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment.
