oxide processing copper options

Gold-Copper Ores - ScienceDirect

2016-1-1 · When ammonia is added to the gold–copper–cyanide system, copper can now exist as either copper(I) or copper(II), since ammonia ligates to copper(II) and helps stabilize this oxidation state. In the presence of sufficient ammonia and copper(I), the copper leach rate was unchanged, but the gold leach rate increased, closely matching the copper leach rate.
