Abstract

The weight of a sample taken from mined minerals and their products is usually determined by empirical formulas of the form Q = kd . A number of researchers have developed and offer theoretical formulas for this purpose, the derivation of which is based on the regularities of mass phenomena studied by the methods of mathematical statistics, in particular, on the regularities of Gaussian, Poisson, and binomial frequency distributions, as well as the theory of errors.
