化念铁矿采用强磁滑轮抛除废石的研究

Study on application of high intensity magnetic pulley in discarding of waste ores in Huanian iron mine

对化念铁矿采用永磁滑轮进行废石抛除的试验进行了探讨，并详细分析了应用永磁滑轮选矿的条件，确定了最佳选矿粒级及工艺流程，为中、小型矿山从赤铁矿、褐铁矿原富矿中抛除所混入的废石，提供了一条有效的选矿途径。

The experiment on application of permanent magnetic pulley in discarding of waste ores in Huanian iron mine was discussed, the conditions of using permanent magnetic pulley for concentration was detailed, and the optimal separation grain size and process flow were determined. An effective concentration way is provided for discarding the waste ores mixed in rich row ores of hematite and limonite in medium and small mines.
