硫化锌精矿中氧化锌的测定

Determination of Zinc Oxide in Zinc Sulf ide Concentrate

在硫化锌精矿中,锌以不同的赋存状态存在。因此,准确测定硫化锌精矿里面的氧化锌含量是地质找矿及评价选矿工艺流程的重要指标。由于提取氧化锌的复杂性,文章研究了不同的浸取流程浸出氧化锌,并对方法的可靠性进行了验证。结果表明氯化羟胺提取体系对氧化锌的提取效率达99%以上,同时硫化矿物对提取效率影响较小。

In zinc sulfide concentrate,zinc exists in different states of occurrence.Therefore,the accurate determination of zinc oxide content in zinc sulfide concentrate is an important indicator for geological prospecting and evaluation of the beneficiation process.Due to the complexity of extracting zinc oxide,we have studied different leaching processes for leaching zinc oxide and verified the reliability of the method.The results show that the extraction efficiency of zinc oxide with hydroxylamine chloride extraction system isover 99%.Sulfide minerals have little effect on extraction efficiency.
