Standard Practice for Drying of Metal Bearing Ores, Concentrates, and Related Metallurgical Materials for the Determination of Mercury

Importancia y uso:

5.1 This practice is primarily to be used to dry samples for determination of total mercury. It should not be used for determination of sample moisture content. Most sample preparation methods prescribe drying samples at 105 °C, until a constant mass is obtained. The moisture content is determined as the percent mass loss on drying. Because mercury and some of its compounds are volatile at 105 °C, samples for mercury determination shall be dried at 60 °C (see Practice E877, ISO 9599, ISO 12743, and ISO 10251).

5.2 It is assumed that all who use this practice will be trained analysts capable of performing skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882.
