目前矿物在显微镜下的定量一般采用数颗粒法,但实际精度只达到半定量的水平。白云鄂博西矿是稀土、铌、铁等的综合矿床,已知矿物有100多种,由于某些有用矿物含量很低,加上矿石在破碎过程中泥化率较高,给矿物定量带来很大困难。我们针对该矿区矿物成分,结合光、薄片鉴定和化学全分析结果对铁、锰、钛、钡、锶、钙、硅、磷、稀土、铌、锆等主要元素进行了物相分析。根据各元素物相分析结果和矿物组 At present, the quantitative determination of minerals under the microscope generally uses the number of particles method, but the actual accuracy only reaches the level of semi-quantitative. The Baiyunebo West Mine is a comprehensive deposit of rare earth, niobium and iron. There are over 100 known minerals. Due to the low content of some useful minerals and the high rate of mudification of the ore in the crushing process, the ore is quantitatively brought Very difficult. We conducted a phase analysis of the main elements of iron, manganese, titanium, barium, strontium, calcium, silicon, phosphorus, rare earth, niobium, zirconium and so on according to the mineral composition of the mine, combined with the light, thin film identification and chemical analysis results. According to the elemental phase analysis results and mineral groups
