Introduction
Gravity spiral chute is suitable for sorting materials with 0.3-0.2 mm granularity, for example iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten ore, tin, niobium mine and other metals which specific gravity differences such as non-ferrous metals, rare metals and non-metallic mineral. For the materials to be sorted, spiral chute separator is also called tungsten spiral chute, tin ore mineral spiral chute and gold mineral spiral chute.

Working principle

Ore pulps are uniformly fed into spiral chute and form different layers as they pass across chute. Heavy minerals flows into bottom and are moved toward inner edge by the comprehensive action of various forces; light minerals are moved toward outer inner becasue the speed rotation. So mineral particles with different density are divided into three zones------concentrate, middling and tailing.

Spiral chute is suitable for treatment of 0.6-0.02mm lode and placer, but high mud content is bad for separation. At present, spiral chute has been widely used in the treatment of iron ore, tungsten, tin ore, niobium tantalum ore, coastal and riverside placer and gold ore.
