FIELD: metallurgy.
SUBSTANCE: invention relates to extraction method and utilisation of palladium, silver and copper of waste electrolytes, containing thiourea, sulfuric acid, water and sludge. Method includes addition to waste electrolyte 33.0-67.5% hydrogen peroxide and blending with transfer of palladium and silver into sediment. After appearance of green colouring in its solution is cooled and filtered. Sediment is anneal and received alloy from palladium and silver.
EFFECT: receiving of ability of quantitative isolation from electrolyte of palladium and silver in the form of metals, which are in the sequel can be used in industrial aims.
