1. A method for co-producing blister copper by enriching germanium and indium from a copper sulfide ore, comprising the steps of:
(1) mixing a copper sulfide ore containing germanium and indium, a reducing agent and a fluxing agent in proportion, and grinding the resulting mixture;
(2) subjecting the mixture to reduction matte smelting to obtain volatile smoke containing germanium and indium and copper matte respectively, and collecting the volatile smoke containing germanium and indium by a bag;
(3) subjecting the copper matte to oxygen-enriched blowing to volatilize germanium and indium to obtain the blister copper and volatile smoke containing germanium and indium, respectively; and
(4) oxidizing fumes discharged from bag dust collection by ozone, and absorbing them by spraying alkali liquor to reach up-to-standard discharge.
