| 摘 要： | 在测定硫化铜矿中自由氧化铜的含量时,容易造成自由氧化铜结果偏高,原因是次生硫化铜矿物的部分溶解而产生干扰。本文选择乙酸?硫酸羟胺溶液作为分离测定硫化铜矿物中自由氧化铜的选择性溶剂,不仅对提高赤铜矿等氧化铜矿物的浸出率有良好效果,而且对抑制次生硫化铜矿物的部分溶解而产生的干扰也有明显作用。

| Abstract: | When determination free copper oxides contained in copper sulphides,the result of free copper oxides tends to be high,which is caused by disturbance generated from partial dissolution of secondary cupric sulfide minerals.In this article,ethanoic acid-hydroxylamine sulfate solution is selected as selective solvent to take in the separation determination of the free copper oxides in copper sulfide minerals,which not only improves leaching of copper oxide minerals effectively,but also suppresses the disturbance from partial dissolutions of secondary cupric sulfide minerals obviously. |
