Abstract
In a process for the extraction of alumina from aluminiferous materials such as kaolin, marl, clays, shales, feldspars, and impure bauxite involving the formation of a clinker of sodium aluminate, the ground clinker is leached with an aqueous solution of a soluble sugar. The ground mineral may be mixed with lime, if little or no calcium be already present, and enough aqueous sodium carbonate to cause all the aluminium to form sodium aluminate. The resulting slurry is dried, sintered, and ground. A solution of sodium carbonate is added to bring the Na2O/Al2O3 ratio to between 1.5 and 1.9 to 1, sugar being added to the solution in the proportion of 0.2 to 2.0 per cent by weight of the sinter. The sugar may be maltose, dextrose, or sucrose, or comprise molasses or corn syrup. The resulting solution of sodium aluminate is separated from the insoluble residue, and may be treated with carbon dioxide to precipitate aluminium hydroxide, the by-product sodium carbonate being used in the earlier stages of the process.
