碱熔离子交换-电感耦合等离子体质谱法测定多金属矿中痕量稀土元素杨小丽1,崔森1,杨梅1,李小丹1(1.湖北省武汉市武汉地质矿产研究所)摘 要:采用碱熔-离子交换法处理多金属矿化样品,建立了电感耦合等离子体质谱法(ICP-MS)测定多金属矿中稀土元素的分析方法.对仪器最佳工作参数进行了优化,探讨了离子交换的速度,洗提液对样品分析结果的影响.实验表明,采用离子交换法分离和选择适当的同位素消除了基体干扰和质谱干扰,用铑,铼作内标元素,有效的抑制了分析信号的漂移.用该方法测定以锌为主的多金属矿石和以铜为主的多金属矿石标......
云南部龙锡锌多金属矿床矿化趋势分析及成矿规律 伍伟1,张文源1,贾福聚1,杨晓坤1,秦德先1 (1.昆明理工大学,矿产地质研究所,昆明,650093) 摘要:结合Surpac软件的空间定位功能和Map Gis软件的空间分析功能,对云南都龙锡锌多金属矿床锡和锌样品数据进行三维空间定位和趋势分析.结合矿区地质特征,认为Sn元素在矿区东部富集程度较高,而且在晚期花岗岩出露部位,发生进一步的富集.Zn元素在矿区西部富集程度较高,而且在断裂交汇部位进一步富集. 关键词:矿山工程; 锡锌多金属矿床; 趋势分析; Surpac; MapGIS; 云南都龙; mining engineering; tin zinc polymetallic deposit; trend analysis; surpac; Map GIS; Dulong in Yunnan Province; [全文内容正在......
