| 摘 要： | 铜丝除钒精制四氯化钛所排废弃物中含有丰富的钒、铜、钛等资源。进一步研究结果表明，该废弃物中铌、钽含量也很高。其中铌含量可达到2.66%，钽含量可达到0.29%，远高于铌钽的工业品位，是一种新型的铌钽资源。该废弃物中的铌钽应为钛铁矿伴生稀有元素，在四氯化钛制备过程中，经过钛铁矿选冶、富钛料高温氯化、粗四氯化钛精制等工艺过程富集而形成。 |
| 关 键 词： | 铌 钽 四氯化钛 废弃物 |

| Abstract: | The waste generated from the process of removing vanadium by copper wires to refine titanium tetrachloride is rich in vanadium, copper, titanium. A further study shows that this waste contains 2.66% niobium as well as 0.29% tantalum. They can be considered as a new type of resource because the contents of Nb and Ta in the waste are much higher than their industrial grades. Niobium and tantalum that may be associated ilmenite enriched in the processing of titanium tetrachloride by the processing of dressing, chlorination and refining. |
| Keywords: | niobium tantalum titanium tetrachloride industrial waste |
