FOERFARANDE FOER SEPARERING AV PALLADIUM FRAON EN BLANDNING AV METALLER TILLHOERANDE PLATINAGRUPPEN

摘要

A method of separating palladium from a mixture of PGMs which contains palladium and at least one other PGM, the method comprising the formation in solution of the amine complexes of the metals present with the metals being in a reduced state and precipitating out the palladium by means of dimethylglyoxime provided that where platinum is present the precipitation is effected at a pH of about 4.0 in the presence of an ammonia absorber.
