摘要: 金岭铁矿铁精矿 TFe 含量为 64.80%,有害元素 S 含量为 0.44%,对该铁精矿进行了脱 硫提质试验研究。以 MK-S 为活化剂,MK-207 为捕收剂,经过 1 粗 3 精脱硫浮选,S 品位从 0.44% 降 低至 0.10%;将脱硫精矿磨至-0.038 mm 占 90%,在粗选磁感应强度为 200 mT、精选磁感应强度为 160 mT 的条件下,经过 1 粗 1 精弱磁选,获得的精矿 TFe 品位为 69.55%,S 品位为 0.08%,全流程 TFe 回收率为 90.73%。研究结果可以为铁精矿脱硫提质提供参考。

Abstract: The TFe content of iron concentrate in Jinling Iron Mine is 64.80%,and the harmful ele⁃ ment S content is 0.44%. The desulfurization and upgrading test of the iron concentrate was carried out. With MK-S as activator and MK-207 as collector,the grade of S was reduced from 0.44% to 0.10% after one roughing and three cleaning desulfurization flotation. The desulfurization concentrate was ground to -0.038 mm accounting for 90%. Under the condition that the magnetic induction intensity of roughing was 200 mT and the magnetic induction intensity of cleaning was 160 mT,the concentrate with TFe grade of 69.55%,S grade of 0.08% and TFe recovery of 90.73% was obtained by one roughing and one cleaning low intensity magnetic separation. The research results can provide reference for desulfurization and up⁃ grading of iron concentrate.
