Изобретение относится к гидрометаллургии благородных металлов, в частности к способам извлечения золота цианированием. Изобретение позволяет повысить извлечение золота из руды при снижении расхода электроэнергии и реагентов. Это достигается тем, что в способе извлечения золота из руд, включающем их измельчение, гидравлическую классификацию с получением иловой фракции и песков, доизмельчение песков с получением кристаллической фракции, сорбционное цианирование иловой и кристаллической фракции с получением хвостов, согласно изобретению, классификацию иловой фракции и доизмельчение песков ведут с выделением песковой фракции + 0,5 мм с последующим ее пассивным цианированием, а сорбционное цианирование иловой и кристаллической фракции осуществляют в автономных циклах.The invention relates to hydrometallurgy of precious metals, in particular to methods for extracting gold by cyanidation. The invention improves the extraction of gold from ore while reducing the consumption of electricity and reagents. This is achieved by the fact that in the method of extracting gold from ores, including grinding, hydraulic classification to obtain a sludge fraction and sands, regrinding sands to obtain a crystalline fraction, sorption cyanide of the sludge and crystalline fraction to obtain tails, according to the invention, classification of the sludge fraction and grinding sand lead with the allocation of the sand fraction + 0.5 mm, followed by passive cyanidation, and sorption cyanidation of the silt and crystalline fractions is carried out independently x cycles.
