Copper Mountain Mine, Princeton BC The Challenge. The SAG/Ball/Flotation circuit was initially designed for 35,000 mtpd. A secondary crushing circuit was installed to exceed the original design and push the mill tonnage rate to 40,000 mtpd. The increased circulating load led to the original SAG Mill discharge screen overloading.
