Abstract: The mass fraction of sericite in flotation tailings from Taiyangping Gold Mine is as high as 50%, making it worth recovering. The experiment investigates and optimizes the sericite recovery process and decides the magnetic separation + hydraulic cyclone classification process be used to recover sericite from flotation tailings and apply it to industrial production. The practice shows that the grade of sericite concentrates is 23.27% and the recovery rate is 48.18%, which are good indexes. The treatment of flotation tailings achieves comprehensive recovery and utilization, reduces tailings emission, increases mining economics.
