Comminution
Soft or finer sized material may not be suitable for these tests and this provides an engineering outcome in itself (i.e. the ore is soft and will require very little crushing energy). Autogenous Media Competency Tests (AMC) – 180 kg of PQ core. JK drop-weight test – Typically, 50-90 kg of ROM ore (or crushed HQ or PQ core). SMC Tests.
