Volume mass (weight)

Volumetric mass (weight) sample small ore mass (weight) samples of the original ore should generally be collected in the borehole or tunnel. The sampling volume is not less than 60 cm ³ , and the ore with uneven structure should be appropriately increased in volume. In the detailed exploration stage, the number of samples shall be no less than 30 for each major ore type or grade in the ore body. Each sample is tested for both S and other estimated resources/reserves and affects the mass (body weight) of the components to investigate the relationship between volumetric mass (weight) and grade. The small volumetric mass (weight) of powdered pyrite ore can be collected from various prospecting projects according to its distribution. The sampling volume is generally not less than 200 cm ³ . If iron ore powder sulfur development, during the exploration phase, to add one to three large volume mass (weight) sample. The sampling volume is not less than 0.125 m ³ . At the same time, a small volume mass (weight) sample and a chemical sample were used to demonstrate the sampling method and representativeness of the large volume mass (weight) sample. The humidity is measured while collecting the volumetric mass (weight) of the powdered pyrite ore, and the season or climatic conditions of the sampling are recorded.
