FIELD: metallurgy.
SUBSTANCE: method includes stage of contact of the material containing precious metals in suspension or solution for leaching, containing ligand, selected from dithiooxamide (rubean hydride acid) or displaced dithiooxamide. Leaching of the platinum group metals, gold and silver from ores containing said metals is performed in water alkali conditions.
EFFECT: exclusion of the corrosion acid conditions of the process of precious metals extraction, and exclusion of cyanide use.
