FIELD: metallurgy.
SUBSTANCE: method relates to metallurgy of precious metals. Method involves pulverizing precious metal concentrate in dilute hydrochloric acid. Reaction mixture is heated at temperature of 80–100 °C for 30–60 minutes. Oxidizer is then introduced, which is by-product of refining production, saline solution containing sodium chlorate and sodium chloride.
EFFECT: dissolution of noble metal concentrate without use of chlorine to obtain affinity salt of palladium with minimum content of impurities of platinum and its satellites.
