METHOD OF SELECTIVELY RECOVERING PALLADIUM Russian patent published in 2004 - IPC

Abstract RU 2231568 C1

FIELD: hydrometallurgy.

SUBSTANCE: palladium is selectively recovered from solutions by precipitation with water-soluble xanthogenates followed by refinement of palladium precipitates to remove impurities. Refinement is carried out at 40-75^оС using repulping in solution of 10-50 g/dm³ thiocarbamide and 20-50 g/dm³ hydrochloric acid.

EFFECT: increased selectivity of recovery from different-composition solutions containing platinum, silver, and copper.
