NTIS: PB/80-110430 :103 pages
This report describes the application of a new membrane process-- coupled transport--primarily to separate and concentrate copper from dump leach liquors. The conditions for which copper was separated and concentrated from copper-iron solution were typical of those used in the hydrometallurgical-electrowinning process for extracting copper. An economic assessment based on results from small, bench- scale hollow fiber membrane modules indicates that processing copper leach liquors with coupled transport membranes should be competitive with the best current technology. Further feasibility studies were performed with uranium, iron, aluminum, and nickel-cobalt solutions. The process appears to be applicable to these solutions as well.
