  • How to use Gy's Formula in Mineral Sampling Minimum

      What is ore sampling? Sampling is a procedure by which some members of a population are selected as representative of the entire population In mining, we select portions of the material in such a manner to ensure that is the true representative of the entire ore For example, suppose you have collected ten different portions use Gy’s Formula in Mineral Sampling Minimum Sample Mass

  • Sampling practice and theory Mine

      Sampling is defined as taking a small portion of a whole mass that accurately represents the whole mass this rarely represents what one would sample in "the real world " of mining and mineral processing dispersed with a pattern or without any pattern Other types of ores can vary less in composition, but almost no ore is homogenous

  • Mineral Sampling ScienceDirect
