test methods for characterizing ore comminution

test methods for characterizing ore comminution

Comminution test methods used within mineral processing have mainly been developed for selecting the most appropriate comminution technology for a given ore, designing a grinding circuit as well as sizing the equipment needed. Existing test methods usually require comparatively large sample amounts and are time-consuming to conduct. 2 is a large copper producer. The comminution circuit at Mine 1 consists of a partial pre-crushing circuit before an SABC circuit followed by three ball mills, whereas Mine 2 is a traditional SABC circuit consisting of a single SAG mill closed with a recycle crusher and followed by two ball mills. The energy curve methodology has been used to
