Mineral processing - Wikipedia

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" [3] ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

Ore Processing Challenges in Gold Operation Grinding Circuits

Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput. This is essential for driving the overall efficiency of the operation because the process of grinding and crushing ore — known as comminution — is on average the highest energy step in mining.
