Автор Dmitriev I. V., Krupnov L. V., Kudrin Е. G., Petrov A. F., Lapshina N. A.

Industrial tests of aged pyrrhotine concentrate processing stored under a water sheet Kajerkansky coal strip mine and pyrrhotine concentrate of Talnahsky concentrating factory in hydrometallurgical production of Nadezhda metal plant are conducted. Extraction of non-ferrous metals in a sulphidic concentrate during the tests has raised. Losses of copper, nickel and cobalt with true tails of hydrometallurgical production have been lowered. Losses of platinum metals on the sum of five elements (Pt, Pd, Rh, Ru, Ir) in comparison with a standard mode were reduced during the tests. Results of tests have shown technological efficiency of the tested technical solution.
