sag mill circuit in iron ores

Developments in iron ore comminution and classification

The additional charge weight due to steel media in an SAG mill must be considered in the mill design, and if an AG mill is to be converted to an SAG mill, modifications may be required. Many circuit configurations are possible, but essentially, AG and SAG mills can be operated as a single-stage primary mill or can be followed by secondary milling in a ball, rod, pebble, or stirred mill.

Gold extraction

Of the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit. The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates.
