Flowing film gravity separation devices, including sluices, spiral separators and come concentrators have undergone significant development over the past two decades, and are now well established technology in the processing of a wide variety of fine mineral feeds. The recent resurgence of interest in cone concentrators has resulted from a recognition of the benefits that this high-capacity and low-cost separator offers. These attributes are re-examined with reference to a number of recent innovative applications. The benefits of high unit capacity are also reflected in the evolution of high capacity spiral separators which similarly offer operational simplicity and plant sizing and cost savings. These benefits are accompanied by demonstrable gains in metallurgical performance. Examples of recent applications of high capacity cone and spiral systems are examined and metallurgical performance data presented.
