摘　　要：对于弱磁性矿石,通过一般的磁选机难以选别出其中的铁矿石,研究选择高梯度磁选机来磁选,就能有效将其中的磁性物料选别出来,对典型的弱磁性矿钛铁矿及赤铁矿制定了相应的高梯度磁选工艺,充分发挥在选取弱磁性矿石上的优势。研究结果表明,在相同的磨矿细度下,分选的矿物品质为6.0 m/s2的始终最小。随着磨矿细度的增加,矿物的回收率和品质都在下降。在磨矿细度为70%的时候,矿物的品质和回收率最佳。随着矿浆流量的增加,分选矿物的品质和回收率下降,品质为9.0 m/s2稳定在30.18%左右。在矿浆流量为6.4 L/min时,矿物品质和回收率最佳。可见研究提出的基于高梯度磁选工艺的弱磁性矿物采矿方法,在选矿采矿上具有有效性,对弱磁性矿物采矿效率的提高具有参考意义。For weakly magnetic ores,it is difficult to separate the iron ore through ordinary magnetic separators.By studying the selection of high gradient magnetic separators for magnetic separation,the magnetic materials can be effectively separated.Corresponding high gradient magnetic separation processes have been developed for typical weakly magnetic ores such as ilmenite and hematite,fully leveraging the advantages in selecting weakly magnetic ores.The research results indicate that,under the same grinding fineness,the mineral quality sorted is always the smallest at 6.0 m/s2.As the grinding fineness increases,both the recovery rate and quality of minerals decrease.When the grinding fineness is 70%,the mineral quality and recovery rate are optimal.With the increase of slurry flow rate,the quality and recovery rate of sorted minerals decrease,and the quality stabilizes at around 30.18%at 9.0 m/s2.When the slurry flow rate is 6.4 L/min,the mineral quality and recovery rate are opti-mal.It can be seen that the weak magnetic mineral mining method based on high gradient magnetic separation technology proposed in the study is effective in mineral processing and mining,and has reference significance for improving the efficiency of weak magnetic mineral mining.
