| 中文摘要: |
| 松树岗钽铌矿床位于下扬子陆块江南古岛弧带东南部，钦杭东段北部成矿带之怀玉山钽铌多金属萤石-磷-滑石非金属成矿亚带内，为灵山地区重要的稀有有色金属矿床。目前矿区查明的钽铌矿资源储量规模位居亚洲首位，矿石类型有钠长石化花岗岩型和云英岩化花岗岩型两类。云英岩化花岗岩型矿石中钽铌品位较高，但其物质组分较复杂、赋存形式不明，本文采用扫描电镜分析仪及系统处理技术(MLA)对矿区云英岩化花岗岩型钽铌矿石的化学成分、矿物组成、嵌布特征及赋存形式等方面进行详细研究，这为矿产综合利用、选矿工艺等方面的选择提供了理论依据。 |
| 英文摘要: |
| The Songshugang tantalum-niobium deposit is located in the southeast part of Jiangnan Island Arc Belt of Lower Yangtze Block and is located in Huaiyushan Tantalum-Niobium polymetallic metallogenic and .uorite-phosphorite-talc nonmetallogenic subbelt of the north part of the east section of Qinzhou-Hangzhou metallogenic belt. It’s a primary rare metal deposit in Lingshan Area, which holds super large tantalum-niobium ore resources. The types of the ore are mainly the albitized granitie type and greisenization type tantalum-niobium ore. The grades of Tantalum-Niobium in the greisenized granite type are relatively high, but the substance composition is a little complex and the occurrence is unknown, so a lot of analysis and testings such as SEM and MLA, etc. are carried out to research the chemical composition, mineral composition, dissemination characteristics, magnetic analysis and occurrence of the greisenization type tantalum-niobium ore in Songshugang mining area. The detailed process mineralogical characteristics research has provided theoretical information for the comprehensive utilization of mineral resources and mineral processing technology of Songshugang tantalum-niobium ore. |
