Description

technical field [0001] The invention relates to a nonferrous metal smelting device and process method. In particular, it relates to a large-flow rapid purification device and method for ammonia method and ammonium salt method electrolytic zinc leaching solution, especially a self-grinding drum replacement reactor and an anti-returning multi-energy cascade purification process. Background technique [0002] The purification of electrolytic zinc leachate is the pre-process of electrolysis. Under the conventional method, the leachate replacement reactor is a stirring purification tank, and the replacement agent is zinc powder. The purification method is to control a certain temperature and pH value, and add an appropriate amount of zinc powder. Under contact with high potential impurity metal ions in the leach solution to produce a contact replacement reaction, reduce the impurity metal lead, copper, nickel, cobalt, etc., and reduce the content to a certain level, and at the sa...
