The invention relates to a method for leaching chalcopyrite and corresponding leaching agent, belonging to the metallurgy technical field. The invention mainly adopts dihydroimidazol phosphate ion liquid ([BMIM]H2PO[4]) as leaching agent, matching with certain partial pressure of oxygen to leach the chalcopyrite, the leaching temperature is between 50 DEG C and 90 DEG C; the leaching pressure is normal pressure; the chalcopyrite granularity is between 100 and 200 meshes; the leaching time is 6-12 hours, the leaching rate of the copper is more than 95 %. The effect of the invention is that the reactor of the invention need not high temperature and high pressure devices, without adding catalyst or oxidizer, the impurity content in the leaching solution is less. the wastage of the leaching agent during leaching is less, the separation of the copper and the impurity is easy, the leaching agent can be used circularly, the production costs and the pollution can be reduced.

The invention discloses a method for reducing the concentration of lead ions in a lead electrolyte. The method is applied in an electrolytic refining process of lead and comprises the following steps: (1) casting by virtue of a vertical die to obtain anode plates of which sizes are 1210*810*27mm and preparing cathode starting sheets of which sizes are 1370*840*(0.85+/-0.05) mm by virtue of a cathode sheet processing machine; (2) arranging pitches between the newly manufactured cathode starting sheets and the anode plates by virtue of an automatic pitch arranging machine, loading into a tank, switching the direct current on and electrolyzing for 3.5-4 days; and (3) taking the cathodes out, reloading the newly manufactured cathode starting sheets, continuously electrolyzing for 3.5-4 days and taking the cathodes and residual anodes out so that an electrolytic period is completed. The method disclosed by the invention has the characteristics that the effect of reducing the concentration of ...

The invention relates to a process for improving the leaching rate of germanium in germanium-containing secondary zinc oxide, and belongs to the technical field of hydrometallurgy. The method comprises the following six main steps: (1) grinding and slurrying germanium-containing secondary zinc oxide smoke dust, (2) leaching germanium-containing secondary zinc oxide subjected to slurrying with a medium-low acid, (3) enriching germanium in leached clear liquid, (4) oxidizing germanium-poor liquid to precipitate iron, (5) returning part of precipitated iron underflow to the low-acid mixed leaching, and (6) carrying out high-acid leaching on low-acid leached residues. And enabling insoluble sulfides in the germanium-containing secondary zinc oxide to react with iron in the iron precipitation underflow to enter the solution. Aiming at the problem of low leaching rate of the traditional two-stage countercurrent leaching process flow, the germanium leaching rate is effectively improved by adjusting ...
