First ground to a fine powder, the ore is next concentrated using magnetic separation and flotation to 60 to 65 % iron, then rolled into 3/8" dia pellets that are purplish-grey when they emerge, steaming, from the plants. Turning low-grade crude ore into high-grade concentrate requires a means of separating the iron particles from the waste rock.
