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 relates to an application of a hydrogen sulfate imidazole ion fluid in copper electrolysis refining. The hydrogen sulfate imidazole ion fluid is used as an addition agent applied in electrorefining of copper, and the addition quantity is 25 to 50 ppm. Electrolytic copper with smooth surface and high purity can be achieved through adding a slight amount of addition agent in the copper electrolysis refining process. The ion electric conductivity of the addition agent is high, the chemical thermal stability is good, the using effect is good, convenient and reliable, and compared with the traditional addition agents such as bone glue, thiourea and chloride ion, the hydrogen sulfate imidazole ion fluid can improve the electrolytic copper surface appearance, refine the crystal grains and effectively improve the edge crystal effect.

The invention relates to a method for preparing Zn-Ti alloy coating by adopting ionic liquid electrolytic deposition technology. The method solves the problems that the process and equipment are complex, cost is high and coating is uneven in the existing process for producing Zn-Ti alloy coating. The preparation method includes: firstly, an organic compound is mixed with zinc chloride anhydrous, so as to form ionic liquid, then appropriate amount of titanium salt is added, so as to obtain ionic liquid electrolyte; secondly, electrolytic deposition is carried out; thirdly, test piece is washed by acetone and distilled water and then is dried, thus obtaining the Zn-Ti alloy coating. The invention has simple process and equipment and low cost. Zn-Ti alloy coating titanium content of which is controlled to be 1.0-25.4% can be prepared, the coating is uniform, smooth and flat, combination with substrate is firm, process is simple, and requirement on material of equipment is low, energy consumption ...
