为了在贫磁铁矿矿石分选过程中,尽早抛出合格尾矿,以减少工艺设备的负荷,提高金属回收率,降低选矿成本,1980年9~11月,冶金部马鞍山矿山研究院用本院研制的φ1050×425半工业型稀土永磁磁选机在漓渚铁矿进行了现场试验。自磨机排矿3~0毫米以下的产品,浓度为17~20%,经一次选别可丢弃产率为
In order to lean the qualified tailings as soon as possible during the lean magnetite ore separation process, in order to reduce the load of the process equipment, increase the metal recovery rate and reduce the dressing cost, from September to November 1980, the Maanshan Mining Research Institute of the Ministry of Metallurgy Institute developed φ1050 × 425 semi-industrial rare earth permanent magnet magnetic separator in the field test of the Lizhu Iron Mine. Since the mill ore discharge 3 to 0 mm below the product, the concentration of 17 to 20%, by a sorting discardable yield of
