    2021-4-27 · Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.Effect of wash water on the mineral size recovery ,2014-6-10 · The spiral used for the tests is a 7 turn WW-6E from Roche Mining. The set-up used for the experiments is shown in Fig. 1. The feed material is a ground ore from the Mount Wright Arcelor-Mittal mine in Quebec (Hyma and Meech, 1989). The ore is mixed with water and the slurry is loaded into pump box A (see Fig. 1). The slurry is pumped to a distributor at the top of the spiral.
