Abstract: It is of significance for the sustainable development in Meishan Mining Corporation to speed up research and practice on the utilization of fine-grained tailings wetland, to maximize recovery of resources and reduce the fine-grained tailings emissions, and to extend the service life of tailings pond.This not only has a practical significance for the survival and development of Meishan Mining Corporation, but also has a good reference for the domestic mining industry on the comprehensive utilization of tailings.The study on the current total tailings from the dressing plant of Meishan Mining Corporation showed that under the same magnetic fields, the recovery rate by high gradient magnetic separator with horizontal magnetic fields is higher than that of vertical one.Clearly, under an appropriate operating condition, the tailing emissions reduction for Meishan dressing plant and the recycle of the existing tailings can be realized.
