Zusammenfassung:	The invention relates to a separating method of a waste copper-nickel alloy. The method comprises the following steps of: preparing a saltpeter solution, adding excess copper-nickel alloy in the saltpeter solution, standing for 10-30 minutes when the reaction is mild and the solution is neutral at the time, separating the un-reacted alloy block, filtering a product, magnetizing and screening to obtain simple substance copper, and adding a copper-nickel alloy in filtrate to soak in the saltpeter solution to circulate, thereby separating the copper-nickel alloy. The method provided by the invention can be used for separating a copper-nickel alloy with reduced production cost, mild reaction condition, high separation efficiency and less influence to environment.
