This Part replaces YS/T 555.12-2006 “Molybdenum concentrates - Methods for chemical analysis of molybdenum concentrate - Determination of oil and moisture content - Gravimetry 1 Scope This Part specifies the method for determining the oil and moisture content of molybdenum concentrate. This Part applies to the determination of oil and moisture content in loose molybdenum concentrate. The determination range is 0.50%~15.00%. 2 Method summary WEIGH the molybdenum concentrate sample; at (150±5)°C, DRY it to a constant mass; determine the oil and moisture content. 3 Instruments 3.1 Analytical balance: The division value is 0.001 g. 3.2 Drying oven: It has an adjustable temperature-control device, with a temperature error of less than ±5 °C. It also has a blower device which can make the air in the drying oven flow without blowing away the sample. 4 Analytical procedures 4.1 Sample WEIGH 10 g of sample, accurate to 0.001 g. 4.2 Number of determinations Perform 2 determinations independently. TAKE the average. If the two analysis results are out of the error range, re-sample for determination. 4.3 Determination PLACE the sample (4.1) in a dry, pre-constant weight weighing bottle of known ......
