我们用硫酸铜法测定有氧化铁存在时的金属铁含量。但文献中有人指出,此法所用的试剂不仅和金属铁作用,也与其它某些化合物作用,特别是与硫化物、磷化物与沉积矿石中的成份等作用,所以我们对此法进行了研究。我们的主要重点是某些类型的氧化铁(例如褐铁矿及氧化亚铁)能否与金属铁一起变成溶液。在分析铁矿钻浆、烧结矿及海绵状铁时,这类混合物是经常会遇到的。
We used the copper sulfate method to determine the presence of iron oxide in the presence of metallic iron. However, it has been pointed out in the literature that the reagent used in this method not only works with metallic iron but also with some other compounds, especially with sulfides, phosphides and constituents of deposited ores, so we have studied this method . Our main focus is whether certain types of iron oxides, such as limonite and ferrous oxide, can become solutions with metallic iron. Such mixtures are often encountered in the analysis of iron ore drilling, sinter and spongy iron.
