Zusammenfassung:FIELD: noble metal metallurgy, possibly extraction of gold from ores and from their concentration products. ^ SUBSTANCE: process comprises steps of disintegrating ore till fraction size minus 0.1 mm; diluting gold in thiocyanate-permanganate solutions at relation of molar concentrations permanganate-ion to thiocyanate-ion no less than 2 : 1. ^ EFFECT: rapid and complete extraction of gold at significantly decreased cost of process in comparison with process of direct cyaniding. ^ 4 tbl, 1 ex
