FIELD: hydrometallurgy. SUBSTANCE: gold is extracted from low-sulfide ores by contacting ore pulp with granules based on hydrophobic carrier and oil products, separation from rock of oleophilic gold particles by adhesion of the latter by granule surface, withdrawal of granules loaded with gold from pulp, disintegration of loaded granules with solvent and separation of particles of hydrophobic carrier and gold. Hydrophobic carrier of granules is used in form of sulfides preliminarily extracted from ore, and solvent is used in form of kerosene. EFFECT: simplified process of extraction of gold from low-sulfide ores by adhesion, and decreased harmful effect on environment.
