MetE-215 Materials Processing Laboratory EXPERIMENT 1
Grinding should be proper. If the grinding is less than proper (undergrinding), the ground product will be too coarse, therefore not ready for mineral processing. If the grinding is more than necessary (overgrinding), mineral processing may be again more difficult; also energy is wasted and filtration of fine material may create problems.
