The Spiral separator/ spiral chute is the earliest mining machine. It has been used in to classify the granularity 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non-metallic minerals which have a big enough specific gravity difference.
Originally known as Humphreys spiral (after the inventor) a wide range of devices are now available. A spiral concentrator consists of a helical conduit of semi-circular cross-section. Feed pulp of between 15 and 45 percent solids in the size range 3 mm to 75 μm is introduced at the top of the spiral.
All units are commercial duty, gravity concentrators for both alluvial and fine milled hard rock ores. Oro's Helix Sprial concentrators can achieve the highest concentration ratio …
