铜精矿样品的氧化条件及其机理探讨

Study on Oxidation Mechanism and Conditions of Copper Concentrates

摘要: 考察了不同贮存和制备条件对铜精矿样品铜含量的影响,得出在包装密封不良时铜含量因氧化而产生的变化结果及其趋势;根据X射线衍射所作的矿相分析结果,利用X射线荧光光谱仪观察样品中铜、铁、硫化学态的变化,探讨了铜精矿氧化反应的机理。样品变质主要是低价硫、铜、铁离子与空气中的水和氧发生氧化反应所致,酸度增高会促使氧化反应加速进行。

Abstract: The effects of various conditions of storage and sample preparation on the content of copper in copper concentrates has been investigated. It was found that the changes in copper content in samples under bad sealed packing condition resulted fr
