ABC closed circuit, AutogenousBallMillCrusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 2025 mm ore can be accomplished in an autogenous mill.

For instance, in a study conducted on a coppergold orebody, it was found that the power consumption of an AG mill is 25% to 30% lower than that of a SAG mill for the same capacity. Lower power consumption in AG mills can result in significant cost savings, making them a preferred choice in many mining operations.
