This program encompasses the recovery of gold, platinum, iridium, rhodium and palladium from scrap and contaminated laboratory ware, equipment, etc. which may be contaminated by alpha emitters (i.e., uranium, plutonium and possibly polonium or combinations of these), beta-gamma emitters such as fission products or all three sources of radiation. In addition the scrap can be chemically contaminated by base metals, graphite or other contaminants. Osmium, ruthenium or silver are not to be recovered.

Invariably in PGM processing Rh is the last of the group to be removed from the residual solution usually containing only traces of other PGM and major amounts of base metals. The purpose of this invention was to provide a process with both high selectivity and good recovery. The rhodium bearing solution (less than 1,0M solution of HCl) is treated with some ethanol as a catalyst providing hydride ions, and ammonia liquor or gas to a pH about 9. Solution boiled under reflux for at least 2 hours and acidified with HCl to pH 0 or until free acid at least 0,5 moles HCl per litre. Insoluble complex pentammino-chloro rhodium (iii) dichloride is filtered off (Rh(NH2)5 Cl)Cl2. The salt is slurried with water, boiled and NaOH added until precipitate dissolves. pH is lowered to between 8,5 and 9,5 conveniently with NaHCO3 when the base metals precipitate and are filtered off. Solution is cooled and NaNO3 is added - twice stochiometric and HNO3 to pH 1. Heavy white precipitate of Rh (NH3)5NO2(NO3)2 forms and is filtered off. For high purity re-crystallize in water - soluble in hot water and insoluble in cold. Direct reduction to sponge is not possible due to explosion hazard. Therefore convert salt back to the chloropentammine by boiling with concentrated HCl and the chloropentammine rhodium (iii) dichloride is re-precipitated and is calcined to sponge.
