A milling circuit consists of a primary SAG (semi-autogenous grinding) mill that is in open circuit. The product from the SAG mill is fed to the ball mill, with the product from the ball mills being classified in cyclones. The underflow from the cyclones is recycled, with the overflow forming the feed to the flotation circuit.The milling circuit

Autogenous grinding (AG) mills are tumbling mills which do not require a dedicated grinding media and use the ore itself for grinding. Ores which are comprised of sufficient competent pieces are amenable to AG mills. For such ores, AG mills perform crushing, fine and coarse grinding steps of size reduction.

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
