Abstract
Feed mixtures containing one or more platinum group metals are fluorinated to form at least one volatile fluoride product which is separated from the residual solid. Separations of different fluorides may be effected by collecting different fractions of volatile fluorides. Palladium does not form a volatile fluoride and is retained in the residual solid.
