Overview • Biggest single stream Platinum Concentrator in the World (600ktpm). • Decision to build a single stream plant required some ground- breaking technology….. • First: – HPGR installation for a platinum ore body – Gearless drive mills in Anglo Platinum • Biggest: – Primary Gyratory crusher 60’’ with a 1000kW motor – Ball Mills in the world 26’ø x 37.6’ EGL with 17.5MW gearless drive – Centrifugal blower installation in Africa – Mill discharge pumps in SA – 1,45MW motors with gearbox drive – HPGR in Africa with the largest installed power in the world (2 x 2.85MW) 34

Energy Efficient Design • Ultra high rate thickeners for tailings disposal • High efficiency motors installed – More work per unit of electricity consumed • Day-night switches for lights • “Ready to float” material can bypass primary milling stage: – Creates additional primary milling capacity or save energy on primary milling stage – No energy waste to pass sufficiently liberated material through primary mill (incl. metallurgical benefits) 35
