Ernest Henry Mining upgrades Vertimill® cyclone pack

The cyclone pack works together with a fine grinding mill called a Vertimill® to efficiently regrind the rougher concentrate. The cyclone pack acts as a separator, sending product that has been ground fine enough on to further processing, while sending material that is too coarse to the Vertimill® for further grinding.
