Comminution or feed size reduction is typically the first stage of ore processing at mines. Comminution tests are commonly conducted to assess the processing behavior of ore and to aid in process design and equipment selection. Testing for Bond mill work index (BMWi), a measure of the ore grindability, and A*b, a measure of the ore crushability, is common in this regard.
