Chromite beneficiation plants generate large amount of tailings with significant amounts of ultrafine chromite minerals. In the present investigation, Box−Behnken experimental design was used to model the effects of feed rate, feed pulp density and splitter position on the performance of a spiral concentrator for separating the ultrafine chromite values from the plant tailings. …
