随着钢铁工业的进一步发展,要求各国更充分地利用其贫氧化铁矿资源,但目前作为铁矿开采的含铁矿物,最主要的还是磁铁矿这一强磁性矿物。通过弱磁场磁选从贫磁铁矿矿石中获得的铁精矿,常是钢铁工业质优而价廉的原料的主要来源。近二十多年来,生产规模的不断扩大,冶炼对精矿质量要求的不断提高,以及入选贫磁铁矿矿石原料中较难选部分的增加,都促使各国为改进磁铁矿的选矿工艺及其主要选别设备——湿式圆筒磁选机而开展了大量的试验研究工作。 With the further development of the steel industry, all countries are required to make full use of their lean iron oxide resources. However, the most important iron ore minerals currently being mined in iron mines are the magnetite, a magnetite mineral. Iron concentrates obtained from lean magnetite ore by weak magnetic field magnetic separation are often the main source of high quality and inexpensive raw materials for the steel industry. In the recent two decades, the continuous expansion of the scale of production, the continuous improvement of the quality requirements of the smelting and the increase of the harder parts selected from the lean magnetite ore raw materials have all prompted the various countries to improve the beneficiation process of magnetite And its main sorting equipment - wet cylindrical magnetic separator and carried out a large number of experimental research.
