Potential By-Products From Copper Dump And Heap Leaching Operations

Copper dump and heap leaching operations are conducted worldwide for production of substantial amounts of copper Such dumps and heaps contain appreciable amounts of other potentially valuable elements such as gold, Iron, magnesium, manganese, molybdenum, silver, titanium, and uranium. Except for uranium, recovery of these elements has not been attempted to any significant extent However, such recovery merits attention based upon availability of existing chemical techniques. This paper presents some thoughts on possible techniques together with opportunities for commercial applications.
