3. Comminution and Mill Energy Requirements Comminution includes both crushing and grinding. Initially, ore is reduced in size by crushing rock to a size that makes it manageable. Crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. Crushing is usually a dry process, and

process by hydrocyclones. The particles of high-density iron oxides that are near the cut size are fully liberated and do not require further comminution, but they are returned to the mill rather than being removed as final product. A fundamental redesign of the comminution circuit is therefore needed to deal with these intermediate-size dense
