Working Principle. Spiral Separators, which are also called Spiral Concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. The heavy frictional forces slow their velocity. As a result, faster particles higher up in the flow.
1.3 Criteria for size separation New model spiral separators have now been developed that are specifically designed to treat material finer than 0.1 mm (100 µm), (Richards et al., 2000). This fine mineral spiral separator is typically longer than traditional troughs to allow these very delicate processes to produce an adequate separation.
Special Issue Information. Dear Colleagues, Physical separation is one the main methods of recovering valuable minerals from an ore (in addition to flotation and hydrometallurgy). Physical separation includes gravity concentration, classification techniques such as hydrocyclones and air classifiers, solid–liquid separation (e.g., …
Spiral concentrators are gravity-based separation devices used for the concentration of coal, heavy minerals, and ores with a relatively high specific gravity. They work on the principle of the spiral motion of slurry within a specially designed trough, creating a centrifugal force that aids in the separation process.
Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

The experimental results show that the spiral separator is efficient to remove ash and enriched carbonaceous components in coal gasification fine slag by separating feed () into concentrate (81.2%), middlings (8.8%), and tailings (10.08%), where the ash content in tailings is up to 90%, accounting for 18.5% of total ash in feeding.
Spiral separators are used to recover the fine coal fraction (2-mm to minus 325 mesh). They are expected to recover fine coal over a wide particle size range …
Records indicate that spiral separators have been utilised in mineral separation for over 100 years. The Spiral's predecessor, the sluice, has been in use for centuries in different forms and a spiral can be thought of as a sluice wound around a column. The spiral separator is distinguished from the
High Intensity Dry Magnetic Separator. Capacity: 0.2-9 t/h. Application: It is suitable for the separation of weakly magnetic minerals and non-magnetic minerals such as tantalum niobium, tin, manganese ore, chromium ore, rutile, zircon, beach sand, etc.
Introduction: Jig concentrator (jig separator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and agitated.This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. A typical jig consists of a water-filled tank known as …
