Rethinking the value of mill relining - Mining Magazine

03/11/2016  Semi autogenous grinding (SAG) mills, because of their advantages in terms of capital and operating costs, were the natural choice for mines as their primary grinding mill option. Then, in the late 1980s when the price of copper rose quickly from a low of $0.62/lb to a high of $1.62/lb, this substantial increase in price further fuelled the industry demand for larger diameter SAG mills, with mill power
