ABSTRACT:
A system which uses available waste acid process streams from hydrometallurgical extraction processes as absorption media for the direct production of leach grade acid solutions for return to the hydrometallurgical processing circuit for use in liberating metals from metal-bearing materials. The produced acid may have a concentration in the range suitable for processing of metal-bearing materials.
