Our Australian based head office houses the world's largest spiral manufacturing facility and produces over 20000 starts annually. In 2010/11 we manufactured HC33 and WW6 spirals for ArcelorMittal's Mont Wright mining operations in Canada to deliver the largest single spiral order in our history. Spiral Concentrators. Features
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).
Spiral chute concentrator Prominer can provide a full range of spiral concentrator for recovering the heavy minerals from alluvial sand coastal sand minerals and black minerals. It can recover the valuable mineral such as placer gold zircon rutile garnet tin tungsten titano-magnetite chrome and manganese ore.
Spiral concentrators from Multotec efficiently segregate mineral slurries by density and particle size in a range of mineral processing applications. By using gravity and centrifugal force to create this separation spiral concentrators have very low energy requirements and no moving parts.
The spiral chute is usually used in combination of multiple units such as 4 units for a group 8 units for a group or 12 units for a group etc. Multiple units can be combined into a large cluster which can theoretically form an infinite capacity spiral concentrator processing plant. Gravity spiral chute working principle The spiral chute .
Spiral concentrators are normally used in banks of multiple spirals. Typical capacities for spirals run from 1-3 tons per hour of feed for minerals and 3-5 tons per hour for coal. Typical construction of a spiral concentrator is fiberglass and urethane to reduce wear from abrasion. Charles Kubach Mining and Mineral Processing Engineer
The control of spiral concentrators to provide a concentrate with as little as possible fluctuation in grade and recovery while feed parameters are fluctuating is difficult and has not been perfected. Large mineral processing plants consist of hundreds of spiral concen-trators and the adjustment of splitters is time

DOVE Spiral Concentrators are cost-effective high performance gravity concentration separators used for separation and recovery of a wide range of minerals: zircon ilmenite rutile iron ore chromite manganese tin tantalum and tungsten ore silica sands gold copper and base metals and etc. as well as other non-ferrous metals rare metals and non-metallic minerals.
Spiral separator also called Spiral chute is one of low investment gravity separating machine with high processing capacity.Compared with shaking table gold shaking table jig separator spiral separator have advantages like: high processing capacity low cost energy saving user friendlylong lift span. it is widely applied in alluvial gold chrometungstenTin mining plant in AfricaAsia.
Spiral concentrators are capable of sustained recoveries of heavy minerals in the size range of 3 mm down to 75 microns (6 to 200 mesh). They are suitable for use as roughers cleaners or scavengers. Feed rates may vary from 0.5 to 4 tons per hour per start depending on the size shape and density of the valuable material.

Spiral concentrator is one of the simple yet efficient methods of mineral beneficiation which sorts particles according to their specific gravity differences. First commercial spiral concentrator was used to treat chromite ore in 1943. Later in 1943 its use was extended to the mineral sand beneficiation.
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). Large mineral processing plants consist of thousands of spiral concentrators resulting in large plant footprints (capital

Spiral Concentrator Multotec-designed spiral concentrators are used across the world in coal gold iron ore mineral sands platinum and chrome processing plants and other minerals.
Some spiral concentrators especially those used in coal cleaning have the capability of removing the high density material at multiple positions in the vertical spiral. Coal can consist of as much as 50% high density material compared to a typical heavy mineral with only 5% to 10% high density content.
