    The slurry was fed to the spiral via a distributor with an overflow pipe to maintain a constant feed rate into the spiral. This was a closed-circuit spiral test with a sump and pump. During each test, the spiral was run until steady-state conditions were reached before taking the relative density (RD) measurements at the top of the spiral rig.
