<strong>ALTA</strong> 2011 NICKEL/COBALT/COPPER LEACHING OF SULPHIDES 276
RECOVERING COPPER AND GOLD IN CHLORIDE SYSTEM BY NIKKO CHLORIDE PROCESS By Kazuaki Takebayashi, Kazuhiro Hatano, Hiroshi Hosaka, Yoshifumi Abe JX Nippon Mining and Metals Corporation, Japan Presenter and Corresponding Author Yoshifumi Abe yoshifumi.abe@nmm.jx-group.co.jp ABSTRACT JX Nippon Mining & Metals Corporation (NMM) has been developing a process which makes copper and gold recovery easy and effective. The process, named Nikko Chloride Process, employs sodium chloride media and is composed of copper leaching and copper recovery, gold leaching and gold recovery and silver recovery. Leaching of copper and gold is performed under ambient pressure with only aeration. Nikko Chloride Process recovers copper by solvent extraction, then produces copper cathode from sulphate solution. Some bromide helps gold leaching from gold bearing copper concentrate. Gold is recovered on activated carbon or by solvent extraction. Silver is recovered by solvent extraction. NMM built a pilot plant for the process in Perth. The pilot plant has operated well. More than 98% of copper is leached and high quality copper cathode is produced. More than 90% of gold is leached. Applying floatation could recover 5% more of the gold from the gold leach residue. NMM is trying to apply gold recovery by solvent extraction. 277
