A method for co-producing blister copper by enriching germanium and indium from a copper sulfide ore comprises: mixing a copper sulfide ore containing germanium and indium, a reducing agent and a fluxing agent in proportion and then grinding; subjecting the mixture to reduction matte smelting to obtain volatile smoke containing germanium and indium and copper matte respectively; subjecting the copper matte to oxygen-enriched blowing to volatilize germanium and indium, so as to obtain the blister copper and volatile smoke containing germanium and indium respectively; and oxidizing fumes discharged from bag dust collection by ozone, and then absorbing them by spraying alkali liquor to reach up-to-standard discharge. In the reduction smelting stage, the volatilization rate of germanium and indium is more than 70%; and in the copper matte oxygen-enriched blowing stage, the volatilization rate of germanium and indium is more than 25%.

A method of extracting a rare earth element from a carbonaceous material deposit utilizing a ligand to capture the rare earth element includes crushing the carbonaceous material deposit to form a carbonaceous material particulate and forming a first pregnant leachate including the carbonaceous material particulate and a ligand. The method further includes extracting the metal impurities via an ion exchange or floatation to form a reduced leachate and forming a second pregnant leachate comprising the reduced leachate and the ligand. The method also includes extracting the rare earth element from the reduced leachate via an ion exchange or floatation, capturing the rare earth element in the binding site of the ligand, and desorbing the rare earth element from the ligand.
