Leaching method of complex zinc calcined ores

The invention discloses a leaching method of complex zinc calcined ores. In order to solve the problems in the prior art that iron is secondarily settled, a great quantity of slag is generated, other impurities are leached out in a great quantity, the ratio of iron to arsenic in the leaching solution is hard to control, the upper middle clear liquid cannot reach the quality requirement, the plate is burned by electrolysis and the like, the method is used for leaching complex zinc calcined ores by adopting steps of acid leaching and neutralizing to remove impurities, so that the purpose of efficiently recovering zinc and removing impurities is reached. Meanwhile, wastewater and waste materials in the prior art are utilized, so that the emission of wastes is reduced and the production cost is lowered. The method disclosed by the invention is simple to operate and easy in process management, reduces the emission of residues or wastes, effectively recovers valuable metals in the leaching process and can selective
