一、前言我们曾用粉末压片的方法测定镍矿尾矿中的镍和铜,对铜取得了满意的结果。但由于镍矿难于磨细,颗粒度效应和均匀性影响使镍的分析结果不够理想。本文采用溶液法,消除了上述影响,同时也基本上消除了试样的基体效应。在选矿流程控制分析中,分析对象有时为水样,溶液法就可以用一条工作曲线同时适应固体矿样和水样的分析。加入内标元素,除进一步消除基体效应 I. INTRODUCTION We have determined the nickel and copper in nickel ore tailings by the powder tabletting method and have achieved satisfactory results for copper. However, due to the difficulty of nickel ore grinding, particle size effect and uniformity of the nickel analysis results less than ideal. In this paper, the solution method to eliminate the above effects, but also basically eliminate the matrix effect of the sample. In the process control analysis of beneficiation, the analysis object is sometimes water sample, and the solution method can use a working curve to adapt to the analysis of solid mineral sample and water sample at the same time. Add internal standard elements, in addition to further eliminate the matrix effect
