The ore weight is also called the ore bulk density, and the ore reserves are calculated as important parameters. Refers to the weight of a unit volume ore in a natural state, expressed as the ratio of the weight of the ore to its volume. According to the measurement method, it can be divided into small body weight and large body weight. The small body weight is determined by the Archimedes principle, and the small block (60-120 cm3) ore is determined by the sealing wax drainage method. The weight formula is:

D—ore weight; W—ore weight; V1—the volume after the wax is sealed, that is, the volume of the wax ore placed in the water;  V2—the volume of the wax sealed on the ore; W1—the ore sealing wax After the weight; 0.93 - the specific gravity of the wax (g / cm3). The small body weight should be 30~50 specimens of type or grade ore. The spatial distribution should be representative; the wax should be sealed in the field, and then the average value should be taken. Since some small cracks and pores (holes) existing in the ore body are not included in the small ore, the measurement result is often larger than the actual ore body weight value, which can be regarded as the ore specific gravity, and often needs to be checked with a large body weight or Correction. The large body weight is taken in the field by the whole lane method, and the weight is W, and then the volume is measured in detail, and the body weight is D=W/V. The volume can be measured by plastic or sand filling, not less than 0.125m3. Although large-weight samples are large in volume, large in workload, and high in cost, for ore with loose or multi-fractured pores (such as oxidized ore, weathered shell-type nickel ore, etc.), each type or grade of ore still needs to measure large body weight 2-4. One. Because the large-weight sample basically represents the natural state of the ore body, it has high reliability and representativeness, and can be used to correct small body weight or directly used for reserve calculation. While determining the weight of the ore, its main elemental grade, humidity and porosity (oxidized ore) are determined.  When tunneling in the ore body, the whole lane method can be used to collect samples; special gross weight measurement can also be carried out in the tunnel or on the surface outcrop. The general sample volume is 1-10 m3.
