METHOD FOR RECOVERING COPPER FROM SULFIDE ORE MATERIALS USING HIGH TEMPERATURE PRESSURE LEACHING, SOLVENT EXTRACTION AND ELECTROWINNING

摘要

The present invention relates generally to a process for recovering copper and other metal values from metal-containing materials through pressure leaching operations. In accordance with the various aspects of the present invention, metal-containing pregnant leach solutions from pressure leaching operations need not be significantly diluted to facilitate effective metal recovery using solvent extraction and electrowinning.
