Gravity Spiral Concentrator Working Principle

The gravity spiral circuit is designed to extract and concentrate “coarse gold’ from the recirculating load in the mill grinding circuit and hence prevent a build up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4) Optimum Operating Conditions of a Spiral Concentrator For the spirals to work efficiently

Georgia Tech spiral concentrator: an innovative design

@article{osti_5856575, title = {Georgia Tech spiral concentrator: an innovative design}, author = {Steenblik, R A and Bomar, Jr, S H}, abstractNote = {A new, low cost, high performance solar energy concentrator has been developed at Georgia Tech. It is based on Fresnel reflector principles, and is formed by slightly winding a flat spiral of reflective material and securing it to a planar frame.

Spiral Concentrator. High Performance Gravity Concentration

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 Concentrators — IMSC Group

The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials, spirals require a minimum of maintenance and upkeep. Spiral concentrators offer a relatively simple unit operation that translates to low capital and operating cost.

Recent research has resulted in the development of mathematical models to predict the performance of spiral concentrators

PARTICLE FLOW MODELLING ON SPIRAL CONCENTRATORS:

The number of turns on spiral concentrators varies typically from 5-7 and the trough width from 0.25-0.35m. The mainstream descent angle varies radially and is governed by the spiral pitch, defined as the vertical height loss per revolution of the helix. The LD9 coal-processing unit examined in this paper has a pitch of 0.273m, trough
