UBC Mining Engineering Graduation Field Trip
Both plants use SAG and Ball Mills to grind the run‐of‐mine ore before the beneficiation process can begin. The grinding circuits of both plants use about 100 MWatts/hour of energy and account for 35% of the total cost of the operation. From the Gold concentrate, Kinross creates their own Dore Bars on site. Each bar weighs approximately 20 kg.
