补充资料：矿石的化学物相分析
矿石的化学物相分析
chemical phase analysis of ore
铁、碳酸铁和硅酸铁，所测得的数据，是矿石中某元素存在于各类矿物的金属量，若按该结果计算矿石中某矿物的质量含量，则应将金属量除以该矿物中某元素的实际含量，或用矿物某元素的理论含量进行估算。对于矿物组成简单的矿石，可以根据矿石化学分析结果，进行矿物量计算，但对矿物成分复杂的就不易准确计算。而化学物相分析可以确定样品中某些元素对」迪上物成分或矿物类别的依附关系。 (程希翱)kuongshl de huoxue wuxlong fenxi矿石的化学物相分析(ehemieal phase analy-515 of ore)用化学的选择溶解法，分析矿石中所含元素以哪种矿物形式存在，并测定其含量的方法。它是研究矿石物质成分和矿石的元素赋存状态的一种辅助方法。按矿石中元素的种类和矿物组成来确定要分析的元素和矿物相。如对氧化铁矿石，一般应分析铁的物相，据此可测定磁性铁、赤铁矿和褐铁矿的铁、硫化
