1. Introduction. Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992).The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, …

Further tests by Diketane et al (2019) on ferrochrome slag showed that the SC25 achieved almost double the separation efficiency than the SC21 spiral at a rougher stage with a feed top size of 3 mm. Diketane et al (2019) also tested the effect of high SG ...

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 Chute Introduction. The spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity of 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals.
