The present work is focused on ion exchange recovery of platinum (II, IV) and rhodium (III) from
acidic chloride solutions in presence of some non-ferrous metal ions and iron (III). It was found out
that 10-fold excesses of nickel (II), cobalt (II), copper (II) and zinc (II) have no interfering effect on
sorption of noble metals, whereas 3-fold excesses of iron (III) can hinder this process and should be
removed from the system. It was determined that platinum and rhodium can be separated and isolated
from accompanying ions of non-ferrous metals and iron (III) by means of simultaneous sorption with
subsequent selective elution by 2 M ammonium thiocyanate and 2 M hydrochloric acid solutions in
