ABSTRACT:
The present invention relates to a process for treating aqueous waste solutions containing complexing or oxidizing agents and dissolved metallic elements or compounds of copper, chromium, nickel, lead or tin. The waste solution is treated with finely divided magnetized ferrous particles, continuing such treatment to allow for homogeneous stirring promoting substantial ion exchange between the solute and ferrous particles, and providing a post-treatment step using an agent to promote precipitation of metallic hydroxides. The precipitates are separated from the solution by deposition in a settling tank and/or filtration.
