Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to ...
Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in water-deficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.

OUR CLAIM: The Multi-Helix Spiral is "hands down" the most efficient gold concentrator available in the industry. It has a proven track record with a recovery rate of 99% of all free gold. It is a commercial duty, gravity concentrator for both alluvial and fine milled hard rock ores and has the highest concentration ratio AND highest recovery rate of any gravity concentrator on the market ...
Spiral concentrators are compact, cost-effective and generally efficient gravity concentration separators for a wide range of applications (for example, coal, beach sands, iron ore, chromite and tantalite). Recent research has resulted in the development of mathematical models to predict the performance of spiral concentrators
from sand and gravel operations and other large placer depos-its will find descriptions of appropriate equipment and byproduct recovery installations. There is also a list of manu-facturers and suppliers for much of the described equipment. Production Gold has .
First commercial spiral concentrator was used to treat chromite ore in 1943. Later in 1943, its use was extended to the mineral sand beneficiation. Since then Spiral design has been progressively modified to improve operational features, extend the range of applications etc (well described by Davies et. al 1991).
1.5 to 0.04 mm may be conducted on spiral concentrators. Spiral plants may consist of multiple stage spirals, depending on the mineral being recovered and the product requirements. Multotec is a leading designer and manufacturer of spiral concentrators. HX High Capacity Mineral Spiral Concentrators • 1 000 mm in diameter

PDF | In a laboratory scale it was studied the possibility to obtain the qualitative feldspar concentrates from albite granites. Mineralogical studies and technological tests were carried out.
Spiral concentrators will tolerate minor feed variations without requiring adjustment. Spiral concentrators, like cone concentrators, are efficient, low-maintenance units that should be considered for any large- scale gravity separation system. The newer Humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns).
The mechanics of separation of spiral concentrators are stated, including the effects of operating parameters. Some of the traditional areas of spiral application are described, together with examples of new applications such as treatment of fine alluvials and tailings, separation of liberated minerals at coarse sizes, and fine coal recovery.
Spiral concentrators are gravity separators usually separating particle sizes between 0.1 and 2 mm in a water carrier medium1,2. The capacities of the spiral concentrators range between 1 and 3 t/h dry solids and recently in excess of 7 t/h in the case of high capacity spiral concentrators when treating typical heavy mineral beach sands ...
In this study, modeling of spiral concentrator for concentrating the ultra-fine chromite was investigated. A three-level Box–Behnken design combining with a response surface methodology (RSM) and quadratic programming (QP) were employed for modeling and optimization of spiral concentrator performance.
