The invention relates to a beneficiation method for recycling nickel metal from waste copper nickel ore. The method is characterized in that the beneficiation method sequentially comprises the following procedures of the open circuit crushing screening procedure, the dry type low intensity magnetic separation procedure, the closed circuit crushing screening procedure, the dry type high magnetic separation procedure and the magnetic separation tailings stirring and filling procedure. By adoption of the method, through waste copper nickel ore stage crushing and stage sorting, in industrial production, the copper nickel ore with the comprehensive nickel grade being 1% or above and the nickel metal recycling rate being 38% is obtained under the situation that the nickel grade of raw ore is 0.24% and the copper grade of the raw ore is 0.06%, the nickel metal can be effectively recycled from the waste copper nickel ore, and 100% of sorted tailings are used for mining filling. The method technology is reliable, cleanliness and high efficiency are achieved, investment is little, benefits are high, the waste ore comprehensive utilization rate is high, and the beneficiation method is an ideal beneficiation method for recycling the nickel metal from waste low-grade copper sulphide ore, nickel sulfide ore and copper sulphide nickel associated ore.
