The Recovery of Chrome and Manganese Alloy Fines from Slag

slag in gravity separation was to look at liberated metal. To do this a modal analysis was employed by using the point counting method. The client needed 90% ferrochrome metal in the product, but the classifier could produce products of grades up to 99%. Atoll™s Canon Engineering plant at Transalloys, had two jigs installed in 1998.
