Mineral and Mining Engineering: What are the differences

Crushing and Grinding are processes that work together to get the rock to be small enough so it can go to flotation. In flotation, they objective is to separate the valuable ore from the waste rock. Crushing is the initial stage of comminution (the action of reducing a material) in mineral processing.
