The present invention relates to a non-metallic mineral separation process, especially process for recovering metals from Mica Mine tailings plant selection. After the tailings powder containing mica is removed by a cyclone or a chute to remove single minerals and cuttings of more than 100 mesh, a slurry having a concentration of 20-40% is prepared, and then an inhibitor, a regulator and a collector are sequentially added. Stir well and pour into the flotation cell for flotation. The method does not need to be delimed in advance, and the mica of more than 90% purity can be obtained by one sorting, and the second selected mica grade is more than 99%, the flotation efficiency is high, the process is simple, and the cost is low.
