### SamplingMineral Processing & Metallurgy

SAMPLING FOR MINERAL PROCESSING. The golden rule states that for correct sampling all parts of the material being sampled must have an equal probability of being collected and becoming part of the final Therefore for a representative sample The total stream should be sampled The sample cutter should intersect the sample at right angles to the flow.
