The SFR System has been proven to increase the overall recovery as well as the coarse particle recovery in scavenger flotation cells. With the automated level control, it is possible for recovery of specific froth depths to be maintained and controlled. Single cell recoveries of 15-36% copper have been demonstrated. From the froth profile, it was determined that the depth that froth is recovered at is critical because there is a variation of copper and molybdenum with froth depth.
