Abstract:
A method of leaching copper-containing ores includes leaching copper-containing ores or concentrates or tailings of the ores or concentrates with a leach liquor in the presence of an additive that enhances the dissolution of copper from copper minerals in the ores and concentrates by forming a complex between (a) sulfur, that has originated from copper minerals in the ores, and (b) the additive. A method of leaching copper-containing ores includes leaching copper-containing ores or concentrates or tailings of the ores or concentrates with a leach liquor includes leaching copper-containing ores or concentrates or tailings of the ores or concentrates with a leach liquor in the presence of a nitrogen-containing organic complexing additive that forms a complex between sulfur, that has originated from copper minerals in the ores, and the additive.

Claim (Index 19):
The method according to  claim 16 , includes forming agglomerates of ore fragments, wherein the additive is polyethylenimine (PEI), and the forming agglomerates includes:\n (a) forming a PEI solution having a pH greater than pH 4.5; (b) optionally heating the solution to at least 50\u00b0 C. to speed up dissolution/dilution of the PEI; and (c) adding the PEI solution to ore fragments at the start of the forming agglomerates.
