Abstract A novel low-intensity pneumatic planar magnetic separator designed to recover and concentrate fine-grained magnetite minerals is investigated and the performance compared with those of conventional wet magnetic separators, i.e., Davis tube tester and drum magnetic separator. The results of the studies show that the magnetite recoveries and grades achieved by the novel planar magnetic separator compare favourably with that of the Davis tube tester. Moreover, the outcomes of the studies show that the magnetite concentrates recovered by the planar magnetic separator showed higher magnetite grades with fewer impurities than that of the wet drum magnetic separator. The findings from the study show that the planar magnetic separator could be a potential laboratory-scale substitute for the Davis tube tester, as well as replace wet magnetite beneficiation technologies in drought-ridden and remote regions where the paucity of water could be a potential economic challenge to wet processes.

评估用于磁铁矿选矿的新型气动磁选机的性能

摘要 研究了一种用于回收和浓缩细粒磁铁矿的新型低强度气动平面磁选机,并将其与传统湿式磁选机,即戴维斯管式磁选机和鼓式磁选机的性能进行了比较。研究结果表明,新型平面磁选机实现的磁铁矿回收率和品位与戴维斯管测试仪相比具有优势。此外,研究结果表明,与湿式滚筒磁选机相比,平面磁选机回收的磁铁矿精矿显示出更高的磁铁矿品位和更少的杂质。研究结果表明,平面磁选机可能是戴维斯管测试仪的潜在实验室替代品,
