根据矿物溶解性质的差异,采用不同溶剂在一定条件下分离提纯单矿物,是一种比较常用的方法。特别是对一些化学稳定性好的矿物(如铬尖晶石、锡石等),通过选择性溶解,常常可以获得质量很高的单矿物。应用化学方法分离提纯单矿物的主要优点是可以较有效地清除某些杂质的干扰,对于提高物质成分研究工作的准确性具有十分重要的意义,所以深受矿床物质成分工作者们的欢迎。有时即使用其他方法提纯了单矿物,为消除某些杂质也用化 According to the difference of dissolution properties of minerals, using different solvents to separate and purify single minerals under certain conditions is a more commonly used method. Especially for some chemically stable minerals (such as chromium spinel, cassiterite, etc.), by selective dissolution, often can obtain high-quality single minerals. The main advantage of using chemical methods to separate and purify single minerals is that it can effectively remove the interference of certain impurities and is of great significance to improve the accuracy of the research on the composition of the materials. Therefore, it is very popular among the workers in the deposit material composition. Sometimes using other methods to purify the single mineral, in order to eliminate some impurities also used
