The utility model discloses a simple and easy convenient cylinder permanent magnetism selects tail ore deposit funnel, including leaking hopper, leak hopper goes into the mine mouth and the bottom slope end for the upper end rectangle structure, the bottom at the slope end is provided with the tailing mouth, the one deck abrasive rubber has been laid on the upper end rectangle lateral wall and/or the inner wall surface at the slope end of leaking hopper. The utility model discloses set up the slope of the bottom of tailing funnel and arrange the tailing mouth lower part of slope bottom in, can effectively avoid magnetic separation continuous production in -process funnel tailing under the ore deposit block up, wear -resistant rubber layer is laid on the rectangle lateral wall and/or the inner wall surface at the slope end of leaking hopper, under proof strength and life's the circumstances, and steel sheet thickness that can attenuate hopper wall, hopper wall needn't adopt dear abrasion resistant steel plate only to need the common plate can in addition to the weight that effectively alleviates the tailing funnel with showing reduction investment cost, shortening the production time, have simple structure, light in weight, with low costs, safe and reliable's characteristics.
