Locked Cycle Testing -Flotation

Locked Cycle Tests. The number of batch tests required will vary from a few on the simple ores to perhaps hundreds for some complex ores. When middling products contain significant quantities of the metals to be recovered, cycle testing permits more accurate recovery calculations by reducing the percentage of middlings that arbitrarily must be assigned to final concentrates or tailings.
