  • Sampling in Mineral Processing Minerallurgy

    In mineral processing, sampling measurements are accomplished for a range of time and space. The data can be plotted in a graph in the form of a random variogram, which can illustrate the degree of spatial or time dependence and also confidence ranges. Sampling cost. Sampling is a compromise between budget and uncertainty level. Because, bringing down the uncertainty level is very required

    01/01/2016· Proper sampling of tectonic deposits of minerals is essential to assess its economic viability of extraction. The sampling techniques used to attain this objective are described in this chapter for varying conditions such as incremental and continuous analysis for particles of different sizes, shapes, densities and for precious metals. Statistical approaches of analytical data are given to interpret

    30/03/2015· SAMPLING • Generally sampling is the process of selecting a part of a whole such that the measured value for the part is an unbiased estimate for the whole. • In mineral processing a whole is referred to as a sampling unit such as mill feed, dewatered concentrate or bullion. • A sampling unit is classified as a dynamic stochastic system when sampled during transfer, and as static stochastic system when sampled

  • An overview of Pierre Gy's contribution to sampling

    On his return to Paris in 1949, his work in a mineral processing laboratory also constantly brought issues of sampling to his attention, in particular the question of ‘the minimum sample weight necessary to achieve a certain degree of reliability’ (Gy, 2004a). In his search through the limited available literature, Gy found that Brunton (1895) claimed that the minimum sample weight was
