| 摘 要： | 通过高温碳热还原分别将高钛渣中的钛和铁还原至富钛相物质Ti2CO和金属铁,并使其中的熔渣相MOx不被还原,然后选用油酸作为捕收剂对Ti2CO/MOx模拟混合原料开展了浮选研究。结果表明,采用该工艺从还原产物中得到了产率79.88%、Ti2CO回收率87.74%的浮选效果。

| Abstract: | Titanium oxides and iron oxides in actual high grade titanium slag were reduced to titanium oxycarbide (Ti2CO) and iron metal respectively by carbothermic reduction, while MOx slag was not restored. Flotation tests of simulated mixed raw materials from Ti2CO and MOx were carried out with oleic acid as collecting agent. The results show that flotation productive rate of 79.88% and 87.74% recovery of Ti2CO were obtained from actual reduction product. |
