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 5):
The method according to  claim 1 , wherein the additive is a compound of formula (II) or a polymer formed from two of more monomers of formula (III): wherein, in formula (II) and (III), R 1 , R 2 , R 3 , R 4 , R 5  and R 6  are each independently selected from a lone pair electron, H, alkyl groups, alkenyl groups, alkynyl groups, or alkylamino groups, or the substituents on each of the two nitrogens together form an alkyl or alkynyl group that connect the two nitrogens to form a ring; R 7 , R 8 , R 9  and R 10  are each independently selected from H, alkyl, alkenyl, alkynyl, OH, alkyloxy groups, alkenyloxy groups, alkynyloxy groups, C(\u2550O)R where R is alkyl, alkenyl or alkynyl, C(O)OH, C(O)OR where R is alkyl, alkenyl or alkynyl, OC(\u2550O)R where R is alkyl, alkenyl or alkynyl, amino, alkylamino, alkenylamino, alkynylamino, C(O)NH 2 , C(O)NHR where R is alkyl, alkenyl or alkynyl, C(O)NR 2  where R is alkyl, alkenyl or alkynyl, or R 7  and R 8  together and/or R 9  and R 10  together may be selected from \u2550O, \u2550NH, or \u2550NH where R is alkyl, alkenyl or alkynyl; and in formula (III), R 1  or R 2  are each independently selected from the groups defined for R 1  and R 2  above or are connected to another monomer of formula (III).
