THE EVALUATION OF A COPPER FLOTATION PLANT .

circuit. Mass balancing of both grinding and flotation circuits was performed to calculate the flow rates in each stream. Laboratory flotation tests were also applied to the ore samples taken from feed of the primary grinding mill to determine the best flotation conditions and to compare the laboratory results with existing conditions.
