本文通过光学显微镜、X射线粉晶照像、X射线衍射分析和电子探针(WDX)分析研究硫镍矿(Ni_3S_2)固溶铜的情况,并用镁添加剂重熔法进行强化析出固溶铜的研究。 硫镍矿同溶铜后,晶胞参数a_0增大0.0435A,C_0增大0.0597A,抛光面上,硫镍矿分为两种:深黄色,含铜约3wt％;浅黄色,含铜0.6-1.5wt％;加镁添加剂处理镍阳极后,硫镍矿基底中辉铜矿粒径可增大六倍,经电子探针(WDX)分析,硫镍矿固溶铜量可降低到零。

In this paper, the solid solution of copper (Ni_3S_2) was studied by optical microscopy, X-ray powder crystallography, X-ray diffraction and electronic probe analysis (WDX) the study. Sulfur nickel ore with copper, the unit cell parameters a_0 increased 0.0435A, C_0 increased 0.0597A, the polished surface, the nickel and nickel is divided into two types: dark yellow, copper about 3wt%; light yellow, containing 0.6 copper -1.5wt%. After the nickel anode was treated with magnesium additive, the diameter of chalcopyrite in the sulfide-nickel base could be increased sixfold. After the WDX analysis, the amount of copper in the sulfide-nickel deposit could be reduced to zero.
