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。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 fluorite-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.
