Magnetic separation is the most efficient separation method of these technologies. Modern magnetic separators are capable of processing up to 500 t ore/h per unit at a very low operating cost (0.3–0.5 kWh power and 2 m 3 recyclable water/t feed ore). Flotation has the advantage of good selectivity, but often it has much higher operating costs ...
