GB/T 27674-2011 Copper,lead and zinc sulfide concentrates—Determination of hygroscopic moisture in the analysis sample—Gravimetric method
Abstract
This standard specifies the determination of moisture content in copper sulfide, lead, and zinc concentrates by the gravimetric method.
This standard is applicable to the determination of moisture content in copper sulfide, lead, and zinc concentrates that do not contain volatile organic flotation reagents (such as kerosene). The measurement range is 0.05% to 2% (mass fraction), and the results are used to correct the analysis results of the moisture-containing samples.
Note: The results of moisture content determination using this standard are not part of the analysis results of the concentrate samples. When it is necessary to determine the moisture content of commercially transported concentrates, refer to the method in ISO 10251. The determination of moisture and moisture-containing water is closely related. In addition, to ensure the correct correction of metal content, the samples in the two determination methods must achieve the same degree of drying.
