The Karara Mine concentrator commenced operation in November 2012 to produce high-grade magnetite concentrate. The circuit consists of three stages of comminution plus magnetic separation at each stage for early gangue rejection. High-Pressure Grinding Rolls (HPGRs) are used for fine crushing, followed by ball mills and TowerMills in secondary and fine grinding duties respectively.

IN-BED GRINDING The energy efficient in-bed grinding provides selective comminution and improved mineral liberation. The ore is fed via an air sealing (1) to the centre of the rotat-ing grinding table (2). Centrifugal forces evenly transport the ore outwards to the grinding zone between the fixed grind-ing rollers (3) and the grinding table.
