Mineral processing Wikipedia. A number of auxiliary materials handling operations are also considered a branch of mineral processing such as storage as in bin design conveying sampling weighing slurry transport and pneumatic transport The efficiency and efficacy of many processing techniques are influenced by upstream activities such as mining method and blending

More2009-1-14 Sampling procedures cover the practice of selecting representative quantities of test material in the field, to evaluate bulk materials. Examples of the test materials are bulk granular solids, slurries, sludges, grains, and solid fuels. It is necessary to be able to sample bulk materials during shipment and during processing operations.

More2017-11-12 SAMPLING: Sampling is the art of securing a small weight of sample as a representative fraction of relatively large lot. To be representative, a sample must contain an adequate number of particles, and the sample must have been selected in a fair way. There are many ways of taking samples either manually or by a machine.
