Abstract:
A method of leaching copper-containing ores, such as chalcopyrite ores, with a leach liquor in the presence of silver and an activation agent that activates silver whereby the silver enhances copper extraction from copper ores.

Claim (Index 29):
A method of leaching copper-containing ores, such as chalcopyrite ores, that includes:\n (a) forming agglomerates of fragments of (i) a copper-containing ore, (ii) silver, (iii) an acid, and (iv) optionally microorganisms, wherein the agglomerate forming step includes any one of (i) mixing together ore fragments and added silver in an agglomeration step, (ii) adding silver to ore fragments and then mixing together ore fragments in an agglomeration step, and (iii) adding silver to the agglomerates after the agglomerates have been formed, and wherein the added silver concentration in the agglomerates is less than 1 g silver per kg copper in the ore in the agglomerates; (b) forming a heap of the agglomerates; (c) leaching the agglomerates in the heap with a leach liquor in the presence of an activation agent that activates silver whereby the silver enhances copper extraction, with the activation agent being any one or more than one ligand such as chlorides, iodides, bromides, and thiourea; and (d) recovering copper from the leach liquor.
