SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines.

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.
The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining. Oxide ores are.
