The study is concern on selective electrowinning of gold from ammonia cyanide leached pulp of refractory copper-bearing gold ore.The optimum process parameters have been achieved:pulp density 20.0%,current density 15 A/m2,lead alloys electrodes as anodes,stainless steel electrodes as cathodes and duration time of 3 hours.The gold can be selectively electrodeposited from ammonia cyanide leached pulp with good morphology and considerable adhesion.By using the prospective process of selective electrinning of gold,the electrowined pulp can be discharged to the tailing dam and the procedures of CCD,carbon absorbing,stripping and electrowinning of gold-bearing carbon can be get rid of,which will reduce much production cost and investment cost.The study will be an important technical basis for the development of refractory copper-bearing gold ore.
