But this is no ordinary mill. With inside dimensions of 36-ft diam. and 19-ft long, this semi-autogenous grinding mill (SAG — see next section) will use a 43-ft diam. ring-gear drive to transmit 18,000 hp and handle up to 3,000 metric tons of copper ore per hour. In short, it will be the largest mill in the world.
