Spiral Separator - Multotec | Mineral Processing
Spirals are widely used in mineral processing as a method for pre-concentration and have proven to be metallurgically efficient and cost-effective. Separation on a spiral is achieved through a combination of forces that act on particles as they move down the trough of the spiral. These forces include gravitational forces, centrifugal force ...

Spiral Concentrators — IMSC Group
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.

Spiral Classifier for Mineral Processing
2015-8-6 · Spiral Classifier for Mineral Processing. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.
