Depending on the type of milling circuit being considered, test work can range from simple determinations based on a small sample of rock or core, up to comprehensive pilot scale testing requiring hundreds of tons of whole ore.
The most commonly used tests are:
- Bond grinding indices (rod, ball and abrasion)
- Unconfined compressive strength
- Impact crushing tests
- Autogenous tumble test
- JK drop weight test
- Pilot scale grinding test
