ABSTRACT:
A process for extracting copper from a compact mass, such as bulk metallic copper and/or copper highly contaminated with insoluble substances, in which the mass of metallic copper is leached with a liquor containing Cu.sup.2+ ions and SO.sub.4.sup.2- ions, the liquor being oxidized separately from the leaching stage, e.g. with oxidizing agents including oxygen-containing gases such as air. At least part of the oxidized liquor is recycled to the leaching stage for the metallic copper. The copper sulfate solution which thus results is recovered.
