Optimising Western Australia Magnetite Circuit Design - Glencore

All of the ore was ground in the AMMTEC pilot AG mill (1.74 m diameter inside liners and 0.46 m EGL) and then run through the magnetic separator. To protect the magnetic separator the AG mill was closed with a 1 mm screen. In the full scale plant it is intended that the AG mill will be closed at a coarser size, up to a maximum of 4 mm.

Mill (grinding) - Wikipedia

A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank),
