APPARATUS AND METHOD FOR COPPER EXTRACTION BY IN-SITU ELECTROLYSIS IN HEAP-LEACHING OF ORES |
摘要 |
Copper is extracted from a heap of low-grade ore by transforming the heap into an electrolytic cell, and imposing a voltage thereon. Anodic conditions of redox and pH cause the sulphide to break down, and the copper to pass into solution. The copper can be recovered elsewhere if the electrolyte is drawn off, or in-situ if allowed to plate onto the cathode. Electrodes are formed as grids of conductors, or as layers of e.g. graphite.
