The determination of the weight of the ore sample required for the test depends mainly on the following factors: the type and nature of the ore, the type of test, the scale and depth, the complexity of the ore dressing method and process, the specifications and capabilities of the test equipment, and the test run time. The weight of the ore sample shall be determined by the test research unit. The following is the general requirement for the weight of the ore sample. (1) Optional test and laboratory small process test The general requirements for the weight of the sample, see the table below. General requirements for the weight of the sample in the optional test and laboratory small process test Hydraulic Tipping Hopper Concrete Drum Mixer
