Inside the mill, the ore is mixed with water in two rotating SAG mills which use the larger rocks and 8-inch steel balls to reduce the ore to about 10 mm or smaller. Then two ball mills grind the ore to about 0.2 mm with 3-inch steel balls. This copper ore slurry is finally pumped to the flotation deck. Asarco milling link -rotary mills.
