Sampling practice and theory

02 08 2014  However this rarely represents what one would sample in the real world of mining and mineral processing I have read many theories of sampling and found one similarity among them the amount and frequency that is recommended for obtaining representative samples is not often within the realm of practicality or feasible with respect to cost and production.
