Silver Recovery from Exhausted Fixing Bath

In A motion picture laboratory, the fixing bath for positive film is usually discarded after fixing approximately 1000 feet of film per gallon of solution. Such a bath will contain a little more than an ounce of silver per gallon, which at the present market price is worth about $0.65. The exhausted fixing bath, may, therefore, contain about $0.75 worth of silver per gallon; in other words, for each million feet of positive film processed, about $750.00 worth of silver is lost in the fixing bath.
