Specifies a gravimetric loss-in-mass method for the determination of hygroscopic moisture content. Applicable to copper, lead and zinc sulfide concentrates with hygroscopic moisture contents between 0.05 percent (m/m) and 2 percent (m/m). This Standard is identical with and reproduced from ISO 9599:1991.

This International Standard specifies a gravimetric loss-in-mass method for the determination of the hygroscopic moisture content in analysis samples of copper, lead and zinc sulfide concentrates.The method is applicable to copper, lead and zinc sulfide concentrates free from volatile organic flotation reagents, for example 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.NOTE 1 The result of the determination of hygroscopic moisture using this International Standard should not be reported as part of the analysis of a concentrate sample. When the bulk moisture content of a commercial shipment of concentrate is required, the method specified [1]should be used. The determination of hygroscopic moisture and the determination of bulk moisture content are connected with each other. In both determinations the same state of dryness has to be achieved, in order to ascertain the correct metal content of a lot.This method is not applicable to sulfide concentrates which are susceptible to oxidation (see 6.3, note 2). Annex A sets out a modified procedure which can be used in this case.
