Comminution Multotec Mineral Processing

The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammerget price

Comminution in the minerals industry An overview

1990-1-1  Abstract. Comminution is the most important unit operation in the beneficiation of ores, its major role being to promote liberation of the valuable from the gangue minerals.
