Abstract

Kola MMC’s Mineral Processing Plant has optimized its product quality control system designed to monitor the mass concentration of non-ferrous metals in the commercial products: i.e. the finished concentrate and the final tailings. Thus, automatic samplers and dividers of Sections 1, 2 and 3 have been made fully conforming with GOST 14180–80; through experiments, variation coefficients have been determined, which were used to specify the homogeneity class for the concentrate and the tailings; operating parameters have been defined for the sampling and sample preparation equipment; through experiments, intermediate precision mean square deviations (Sопр) and intermediate precision limits (RLопр) have been determined. Measurement procedures have been developed that were certified by Rosstandart, Russia’s Federal Agency for Technical Control and Metrology.
