Electrolytic silver recovery system for recovering silver from photographic fixing solutions
 An electrolytic silver recovery system for recovering silver from photographic fixing solutions, by means of an electrolytic cell (28) having an anode (52) and a cathode (53), and circulation pumps (29a, 29b) for removing solution from the cell and returning it to the cell, which device comprises a hydrocyclone (56) located in the liquid path (55) from the cell to the suction side of the pumps and connected at its outlet directly to the suction side of the pumps. The suction pressure of the circulating pump maintains a low pressure differential of less than about 0.6 bar between the inlet and outlet of the hydrocyclone which establishes the liquid flow through the hydrocyclone.
