Abstract
The present invention provides methods and the use of compositions for removing substances from aqueous solutions wherein the pH of said solution is raised from acidic to basic. In these methods a composition containing Fe3+ and Mg2+ as sulfates is added to said solutions before raising the pH to settle said substances. The substances to be removed may be metals or heavy metals, such as complexed Cu-ions.
