Abstract
A method of processing a non-virgin sulfuric acid solution for the preparation of aluminum sulfate comprises the steps of combining a sulfuric acid solution having less than about 90% sulfuric acid with a water solution to form a mixed solution of no less than about 10% sulfuric acid. An alumina-containing compound such as aluminum hydroxide or aluminum bauxite is then added to the mixed solution to form aluminum sulfate.
