    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
