For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
Minto Mine is a high-grade copper and gold mine that is located 240 km north of Whitehorse, Yukon. Operations are ongoing at this time and began in October 2007. Minto processes both open-pit and underground ore using conventional crushing, grinding, and flotation to produce copper concentrates with significant gold and silver credits.
Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill.
Yet when properly applied, these mills can offer economics which might mean the difference between profitable or unprofitable operation. The attraction of semi-autogenous grinding in copper operations is that they can accommodate ores that are hard or soft, wet or dry, sticky or otherwise.
