| description | The invention relates to the technical field of recycling of electroplating sludge, in particular to an ammonia leaching recycling process for copper and nickel in electroplating sludge. The ammonia leaching recycling process includes the following steps of: (1) mixing, filtration and separation; (2) extraction treatment of leaching liquid; (3) secondary extraction treatment of the leaching liquid; (4) impurity removal for a loaded organic phase; (5) back extraction treatment for the loaded organic phase in the first stage; (6) back extraction treatment for the loaded organic phase in the second stage; (7) impurity removal for back extraction liquid; and (8) preparation of a leaching agent. The ammonia leaching recycling process has the advantages of simple process, convenient operation, no secondary pollution, low operation cost, high heavy metal recovery rate, and remarkable environmental benefit and economic benefit.
