中文名称：铜、铅和硫化锌精矿.在分析样品中湿存水的测定.重量法

英文名称：Copper, lead and zinc sulfide concentrates — Determination of hygroscopic moisture in the analysis sample — Gravimetric method

发布日期：1991-02

标准范围

给出的方法适用于不含挥发性有机浮选试剂（如煤油）且吸湿含水量在0.05%（m/m）和2%（m/m）之间的硫化铜、铅和锌精矿。它用于将平衡湿度水平的分析结果修正为干基。该方法不适用于易氧化的硫化物精矿。附录A列出了可在这种情况下使用的修改程序。

The method given is applicable to copper, lead and zinc sulfide concentrates free from volatile organic flotation reagents, e.g. kerosene, and with hygroscopic moisture contents between 0,05 % (m/m) and 2 % (m/m). It is used to correct the analysis results from the equilibrated moisture level to the dry basis. This method is not applicable to sulfide concentrates which are susceptible to oxidation. Annex A sets out a modified procedure which can be used in this case.
