The Humphrey spiral is one of the mineral concentration ma-chines based on gravity separation. The parameters that affect the performance of Humphrey spiral are the feed size, feed solids, feed rate and splitter position [9]. Successful concentration with Humphrey spiral depends on the selection of suitable operating conditions and mineral solids.
