High capacity gravity separators a review of current status

Flowing film gravity separation devices, including sluices, spiral separators and cone 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. cent 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. nefits 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. es of recent applications of high capacity cone and spiral systems are examined and metallurgical performance data presented.
