摘　　要：本文考察了低品位复杂铜多金属矿石在不同试验中不同浸出溶剂对铜含量的变化,逐步确定了硫酸铜相、自由氧化铜相、结合氧化铜相、自然铜、次生硫化铜相的浸出条件。通过样品测定,表明火焰原子吸收光谱法测定铜多金属矿石中各物相中铜含量,方法简单,干扰少,结果准确。测定范围:0.010%~5.00%。The paper investigated the changes of copper content in low-grade complex copper polymetallic ore by various leaching solvents in different experiments,and the leaching conditions of copper sulfate phase,free copper oxide phase,combined copper oxide phase,native copper and the secondary copper sulfide phase were gradually determined.It shows that the determination of copper content in each phase of copper polymetallic ore by flame atomic absorption spectrometry is simple,less interference and accurate through the sample determination.The determination range is 0.010%~5.00%.
