本矿区的钴,经过用各种研究手段证实,是替换镍黄铁矿中的镍而呈类质同象状态存在,也就是说它主要分布于镍黄铁矿中。这一结论还有必要通过化学物相分析来证实。 本文采用本区的主要硫化物——镍黄铁矿(紫硫镍铁矿),黄铜矿,磁黄铁矿(纯度均大寸90％)来作试验,然后将其应用于原矿各类矿石中钴的物相分析。经试验表明,各种溶剂对本区各种矿物的选择溶解情况为:5％H_2SO_4+HF能很好地溶解硅酸盐矿物和磁铁矿而不溶解硫化物;盐酸能较好地溶解磁黄铁
The cobalt in this area has been confirmed by all kinds of research means that it exists in the state of isomorphism instead of nickel in pentlandite, that is to say it is mainly distributed in pentlandite. This conclusion is still necessary to confirm by chemical phase analysis. In this paper, the main sulphides in this area - pentlandite (purple sulfur nickel-iron ore), chalcopyrite, pyrrhotite (90% purity are large size) for testing, and then applied to all types of ore Phase Analysis of Cobalt in Ore. The experiments show that various solvents for the choice of various minerals dissolved in this area: 5% H_2SO_4 HF can dissolve silicate minerals and magnetite without dissolving sulfide; hydrochloric acid can better dissolve magnetic yellow iron
