GB/T 14505 method for chemical analysis of rocks and ores General rules and regulations

3 Principle

Sample after 105 °C drying to constant weight to lose mass is adsorbed water content.

4 Instruments and equipment

4.1 Balance. three, a sense of the amount of 0.1mg.

4.2 cylindrical weighing bottle (diameter 35mm).

5 Sample

According to GB/T 14505 requirements, the maximum particle size of the sample should be less than 74µm.

6 Analysis step

6.1 Determination of the number of The same sample, the general should be measured in duplicate, or by a certain percentage were measured in duplicate.
