| 摘 要： | 陕西省洋县毕机沟钒钛磁铁矿属多金属矿，其中伴生的钪品位达59.65×10-6，可供综合回收利用。采用显微镜鉴定、化学多元素分析、电子探针波谱分析、MLA分析及元素面扫描等手段首次对矿石开展详细的钪元素赋存状态研究，为钪资源的科学评价和综合利用提供重要依据。研究结果表明：矿石中没有独立钪矿物，钪以类质同象形式赋存于载体矿物中，分别为普通辉石、角闪石、阳起-纤闪石、紫苏辉石、磁铁矿和钛铁矿。钪在普通辉石、角闪石等非金属矿物中的分布率总和占84.36%，钪在磁铁矿和钛铁矿中的分布率总和占15.64%。本研究成果揭示可选择主要从尾矿中提取钪，普通辉石、角闪石的分离是提取钪的关键。

| Abstract: | The Bijigou vanadium-titanium magnetite deposit in Yangxian country, Shaanxi province is a polymetallic deposit, among which the associated scandium grade reaches 59.65×10-6, which can be used for comprehensive recovery and utilization. The occurrence state of scandium element was researched by microscope, chemical analysis, electron probe micro-analyzer(EPMA), mineral liberation analyser(MLA) and EDS maps image, etc. The research provided important basis of science evaluation and comprehensive utilization of scandium. The results showed that there was no independent scandium mineral in the ore. The scandium occured in augite, hornblende, actinolite, actinolite-uralite, hypersthene, magnetite and ilmenite in the form of isomorphism. The distribution rate of scandium accounted for 84.36% in non-metallic minerals such as augite and hornblende, while 15.64% in magnetite and ilmenite. The research achievements reveal that augite and hornblende separation technology is the key to extract scandium from vanadium-titanium magnetite. |
