Subsequently, Welsh, R.A. and Deurbrouk, Gravity separation is one of the oldest mineral processing techniques yet, with modern developments, it is still to the fore. Gravity concentration is, essentially, "a method of separating particles of minerals of different specific gravities by reason of their differences in movement in response to the joint simultaneous actions upon them of Gravity separation.

Spiral conditions for the recovery of ultra-fine particles
use of spiral separation technology to treat fine material (80% passing 75 μm), has historically been ineffective at this size range. A fine spiral separator may enable a reduction in the amount of material treated through subsequent processing stages by the rejection of fine liberated gangue material after grinding. 1.2 Design parametersOur spiral separators for heavy minerals, including iron ore, chrome, mineral sands and other high-density minerals, separate particles in the size range 1.5 to 0.04 mm. We have 3-turn, 5-turn and 8-turn spirals with high-, medium- and low-gradient profiles. Our high-capacity spiral separator (the HX series) provides a per-start tonnage ratingSpiral Separator Multotec

Modeling and optimization of spiral concentrator for separation
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 (100%) 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.Other articles where spiral separator is discussed: mineral processing: Gravity separation: forces—for example, centrifugal force on spirals or impact forces on shaking tables. Spirals consist of a vertical spiral channel with an oval cross section. As the pulp flows from the top to the bottom of the channel, heavier particles concentrate on the inner side of Spiral separator metallurgy Britannica
