在评价矿石和选矿产品的物质组成时,金属矿石铁可按可溶铁计算,也可用铁矿物的选择性还原和随后溶解铁的方法测得。在大多数情况下,按可溶铁计算的金属矿石铁快速测定法取得的结果偏高,因为一部分含铁硅酸盐同金属矿物的铁一起被溶解。众所周知,选择性还原法可以得到更可靠的测定结果。但是,在采用这种方法时,为了消除起干扰作用的矿物的影响,必须根据矿石的组成进行各种预处理。这样,有时使得物相化学分析法复杂化,并延长了分析对间。因此,本文作者以苏联科尔舒诺夫和鲁 In assessing the material composition of ores and beneficiation products, the metal ores can be calculated as soluble iron, as well as by selective reduction of iron minerals and subsequent dissolution of iron. In most cases, the rapid determination of iron by metalloxaccum calculated as soluble iron leads to high results as a part of the ferrous silicate is dissolved together with the metallogenic iron. As we all know, selective reduction method can get more reliable determination of the results. However, when this method is used, various pretreatments must be performed according to the composition of the ore in order to eliminate the effect of disturbing minerals. This sometimes complicates the phase chemistry analysis and lengthens the analysis pair. Therefore, the author of the Soviet Union Korshunov and Lu
