Способ относится к гидрометаллургии благородных металлов, в частности к извлечению золота из упорных, преимущественно углистых, сульфидных концентратов. Изобретение позволяет повысить степень извлечения золота. Это достигается тем, что в способе переработки упорных золотосодержащих концентратов, включающем подавление сорбционной активности природных минеральных сорбентов в исходном продукте и его последующее выщелачивание, сорбционную активность природных минеральных сорбентов подавляют цианированием исходного продукта при концентрации цианида натрия в растворе 5 ... 50 г/л и отношение Ж : Т = 0,5 ... 1 : 1.The method relates to the hydrometallurgy of noble metals, in particular to the extraction of gold from refractory, mainly carbonaceous, sulfide concentrates. The invention allows to increase the degree of extraction of gold. This is achieved by the fact that in the method of processing refractory gold-containing concentrates, including suppressing the sorption activity of natural mineral sorbents in the starting product and its subsequent leaching, the sorption activity of natural mineral sorbents is suppressed by cyanidation of the starting product at a concentration of sodium cyanide in a solution of 5 ... 50 g / l and the ratio W: T = 0.5 ... 1: 1.
