在岩石和矿物的化学分析方面,往往要求亚铁的正确的测定值。因为在鉴定矿物时,尤其是在详细地研究矿物的化学组成时,必须把亚铁和高铁加以区别,这两种不同状态的铁,它们在地质学及地球化学上所代表的意义是彼此不同的。同时在决定矿石的工业类型以及在矿石的加工和选矿方面,有时也需要了 In the chemical analysis of rocks and minerals, the correct determination of ferrous iron is often required. Because in the identification of minerals, especially in the detailed study of the chemical composition of minerals, you must distinguish between ferrous and high-speed rail, the two different states of iron, their geology and geochemistry represents the significance of different from each other of. In the meantime, it is also sometimes needed in determining the type of ore industry and in ore processing and beneficiation
