Solving The Mystery Of How To How To Grind Copper

There is always the odd job, or rework that requires manual grinding of copper. One of the main reasons copper is avoided is because it is difficult to grind and it requires additional handwork after machining. This is due to the annoying burrs thrown up by machining, whether by milling or grinding.

Mineral processing

Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material.
