FIELD: metallurgy.
SUBSTANCE: particular invention relates to cyanides leaching of metals, particularly to water cyanide-bearing composition for leaching of metals from its containing materials. Composite contains at least one non-ionic surface active agent. This surface active agent in water solution regulated by means of NaOH up to value of pH from 9.8 up to 10.2, in concentration from 0.01 up to 0.2% wt, at temperature 23°C leads to reduction of angle of capillarity on glass after 1 second to at least 10°. Composite can additionally at least one cationic surface active agent and/or at least one anionic surface active agent.
EFFECT: reduction of duration of leaching and amount of cyanide.
