Copper, lead and zinc sulfide concentrates — Determination of hygroscopic moisture in the analysis s...
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…
General Introduction
One of the key requirements before organizations can exchange administrative, commercial and transport information between their computers, without manual intervention, is agreement on the content and structure of the information to be transmitted. In EDIFACT, this is achieved by developing United Nations Standard Electronic Messages (UNSM's), for both national and…
