 — A SAG (Semi-Autogenous Grinding) mill is a giant rotating cylinder filled with grinding media and the ore being reduced. As the mill rotates, the grinding media lifts and the impact crushes the feed material. SAG mill control refers to the practice of managing the mill load, which is the amount of material inside the mill at any given time.

This quarter's edition investigates the presence of carbon in relation to the processing of primary ores which can be problematical and impact recoveries. Explore why SAG mills are an enigma compared to ball mills.

 — In this paper, we develop a state space model of semi-autogenous (SAG) mill systems, which is of great significance to the mineral processing control.

 — An AG mill is a tumbling mill that utilises the ore itself as grinding media. The ore must contain sufficient competent pieces to act as grinding media. An SAG mill is an autogenous mill that utilises steel balls in addition to the natural grinding media (Wills' Mineral Processing Technology, B.A. Wills, 6th Edition).

Semi-autogenous mill performance is greatly affected by the proportion of coarse rocks in the feed that combine with the balls to impart breakage energy to the mill contents. To a lesser extent, the feed size distribution also determines the proportion of 'critical size' material in the mill which is both too small
