These methods, or ones that have been established togive equivalent results, should be followed.I:\MSC\85\26-Add-2.doc
MSC 85/26/Add.2ANNEX 3Page 337Concentrates and similar materialsIt is clearly important that the samples should be dried to a constant mass. In practice, this isascertained after a suitable drying period at 105 o C by weighing the sample successively with aninterval of several hours elapsing. If the mass remains constant, drying has been completed,whereas if the mass is still decreasing, drying should be continued.The length of the drying period depends upon many variables, such as the disposition of thematerial in the oven, the type of container used, the particle size, the rate of heat transfer, etc.It may be that a period of five hours is ample for one concentrate sample, whereas it is notsufficient for another. Sulphide concentrates tend to oxidize, and therefore the use of dryingovens with air circulation systems is not recommended for these materials, nor should the testsample be left in the drying oven for more than four hours.CoalThe recommended methods for determination of the moisture content are those describedin ISO 589-1974, “Hard Coal – Determination of Total Moisture”. This method, or ones thathave been established to give equivalent results, should be followed.Calculation of moisture content, FMP and transportable moisture limit:Taking m 1 as the exact mass of the subsample “as received” (see 1.1.4.1),Taking m 2 as the exact mass of the “as received” subsample, after drying,Taking m 3 as the exact mass of the sample just above the flow state (see 1.1.4.3),Taking m 4 as the exact mass of the sample just above the flow state, after drying,Taking m 5 as the exact mass of the sample just below the flow state (see 1.1.4.3),Taking m 6 as the exact mass of the sample just below the flow state, after drying,Then:.1 The moisture content of the concentrate “as received” is:( m1− mm12)× 100, in per cent(1.1.4.4.1).2 The FMP of the material is:( m3− m4) m5− m6+m m325× 100, in per cent(1.1.4.4.2).3 The transportable moisture limit of the material is 90% of the FMP.I:\MSC\85\26-Add-2.doc
