Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.

Usual SAG consumption milling mid hardness ores (say WI 16) can expect 300-400gr per tonne of ore milled. Harder ores and media breakage a take these numbers well over the KG per tonne consumption. We have seen (first hand) in access of 3kg/mt, due to unnecessary media breakage due to incorrect media grade/size selection.

1 Introduction. Ore deposits with high content of recoverables are becoming increasingly rare. For some ores, the decrease in metal content is so significant that grinding to particle sizes smaller than 80 micrometres (µm) and below is necessary to ensure sufficient liberation of the ore [1]. Fig. 1 shows an overview of the average copper content in the ore beneficiation plants worldwide ...

There are various comminution methods for mineral processing. Crushing and grinding are common comminution processes, where the main aim is the liberation and reduction of the size of the ore. Crushing techniques make use of cone, jaw or gyroscopic crushers, yet grinding techniques are more often performed by milling, such as SAG or ball milling.
