Initial treatment comprises digesting with aqua regia to produce a solution containing the major portion of the gold, platinum and palladium as chlorides, the residue comprising the more insoluble metals, iridium, rhodium, ruthenium and osmium. The solution is reduced by adding ferrous chloride to remove the gold. The addition of ammonium chloride to the filtrate precipitates impure ammonium chloroplatinate, which is calcined to a crude platinum …
