FIELD: metallurgy.
SUBSTANCE: invention relates to extraction method and utilisation of gold, silver and copper from waste electrolytes, containing thiourea, sulfuric acid, water and sludge. Method includes addition to waste electrolyte 33.0-67.5% hydrogen peroxide and blending with transferring of gold and silver into sediment. After appearance of green colouring in solution it is cooled and filtered. Sediment is annealed and it is received an ally of gold and silver.
EFFECT: receiving of the ability of quantitative isolation from waste electrolyte of gold and silver in the form of metals, which in what follows can be used industrial.
