· RM was highly efficient at sulfide removal (average 75% sulfide removal at initial concentration of ∼5 mg L −1, with 500 mg L −1 RM addition) due to both physical adsorption (high specific area) and chemical reaction (with amorphous Fe).
Alumina Refining | The Aluminum Association
Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.

Bauxite Deposits
Bauxite deposits invariably contain a range of impurities, ranging from organic material to trace elements such as Ga, Zn, Pb, P and Be. Table shows typical compositions of a range of smelter aluminas. In the Bayer process, many impurities are at least partially soluble in the caustic digestion liquor and may be carried over into precipitation if they are not removed in the desiliion ...
