The invention discloses a floated spodumene tailing resource recovering method. Spodumene tailing is pre-pulped, meanwhile, sodium carbonate is added to remove residual chemicals, low intensity magnetic separation is carried out to remove mechanical iron, screening is carried out to form obtain different particle size grades, corresponding deironing equipment for narrow-grade selecting is used forcarrying out two-stage strong magnetic separation deironing, then, concentration and dehydration are carried out, and finally qualified feldspar concentrates are obtained. The floated spodumene tailing resource recovering method has the advantages that waste resources are reutilized, the utilization rate of the resources is advantageously increased, the product quality is stable, no pollution iscaused, zero emission is achieved, the environmental pollution is reduced, environmental friendliness is achieved, the recovering cost is low, the process is simple and efficient, the method is reliable, and the adaptability is high. The recovering of the waste resources is sufficiently achieved, meanwhile, the production requirement of pollution-free zero emission is met, and the floated spodumene tailing resource recovering method is a green and environmental-friendly beneficiation method for achieving utilization of the waste resources.
