Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge.

Comparing strategies for grinding itabirite iron ores in autogenous and semi-autogenous pilot-scale mills. AG/SAG is more efficient than crushing and ball mill circuit for 3 of the 4 samples. Abstract. High grade iron ore resources are becoming depleted in Brazil, with relatively low-grade ores requiring more intensive comminution for

physically separated into iron ore and impurities in the downstream sub-process. In many cases, an autogenous mill (AG mill) or a semi-autogenous mill (SAG mill) is used for the primary grinding, and a ball mill is used as the secondary for further grinding. An AG mill uses larger rocks of ore, while an SAG mill uses both larger rocks of ore and

The extracted ore material will undergo primary crushing in a gyratory crusher and stockpiled. The ROM stockpile will be transported for grinding via conveyor belts to two semi-autogenous grinding (SAG) mills which in turn will feed two ball mills. The SAG screen undersize and discharge from the ball mill will be fed into cyclone clusters.
