Title from cover. Includes bibliographic references. "The use of commercially-available precision metering pumps makes possible the continuous argentometric titration of free cyanide in process solutions. End-point indication, provided by continuous measurement of the potential of a silver wire-reference electrode combination, gives a good approximation of the actual cyanide content of the samples and, further, is ideally suited to automatic control of cyanide addition to the process. The response time is of the order of 2 minutes, but could be reduced. The procedure requires a clarified solution and is not applicable to unfiltered ore pulps or slurries"--Abstract.
