| titleOfInvention | A kind of chloride system hydrometallurgical zinc process |
| abstract | The invention discloses a hydrometallurgical zinc smelting process with chloride system, which belongs to the technical field of hydrometallurgy. The invention uses chlorine gas as a leaching agent to leaching raw materials of zinc oxide and zinc sulfide, and after leaching, zinc chloride is obtained as the main component. Aqueous solution, remove impurities such as lead, copper, indium, etc. in the aqueous solution to obtain zinc chloride electrolyte, pump the electrolyte into the electrolytic cell for electrolysis, and the gas precipitated by the anode is transported to the leaching process through pipelines, and the raw materials are leached, Metal zinc is precipitated at the cathode, and the metal zinc is peeled off from the surface of the cathode to obtain a product zinc plate. In the whole circulation process of the present invention, the chloride system is used, and the zinc-containing material is leached with chlorine gas as the leaching agent, and electrolysis can be carried out under neutral-weakly acidic conditions, the electrolysis period is long, the process route is simple, and there is no crystallization, etc. Troubled by failure, high product yield and wide material sources, it has good economic benefits and market prospects. |
