cn104294057a method for extracting gold from copper,the invention discloses a method for extracting gold from copper-oxide oxidized gold ores. the method comprises the following steps 1, carrying out ammonia-cyanide leaching on the copper-oxide oxidized gold ores to obtain an ore pulp 2, adding hypochlorite into the ore pulp, and stirring to remove copper in order to obtain a copper removed ore pulp 3, carrying out countercurrent washing on.flowsheet gold processing,the processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviourflowsheet options for processing copper gold this paper presents experimental results of flowsheet designs excluding cyanidation to maximize the gold. recovery for a.
