<p>PROCESS FOR EXTRACTING NOBLE METALS The invention provides a hydrometallurgical process for extracting noble metals from raw materials containing the same, comprising residue containing the noble metals, b) treating said residue with a substantially non-aqueous liquid comprising bromine and an apolar organic solvent in which bromine dissolves to form a complex of the formula R¢MeBrx! wherein x = 4 - 6 Me = Au, Ag, Pt, Pd Os, Ru, Rh, Ir and R is an organic moiety of the solvent, and c) subjecting the complex-containing substantially non-aqueous liquid to electrolysis whereby noble metal is deposited on the cathode and removable therefrom and bromine liquid is formed at the anode and immediately dissolves in the organic solvent.</p> |
