Spiral concentrators are gravity-based and used to separate low-density granular and sandy (from 18 mesh to 200 mesh—1 mm to 0.0757 μm) materials from higher-density materials. Spiral concentrators are used in many mineral processing applications. For instance, they're used to process heavy mineral sand deposits, more specifically …
The spiral used for the tests is a 7 turn WW-6E from Roche Mining. The set-up used for the experiments is shown in Fig. 1.The feed material is a ground ore from the Mount Wright Arcelor-Mittal mine in Quebec (Hyma and Meech, 1989).The ore is mixed with water and the slurry is loaded into pump box A (see Fig. 1).The slurry is pumped to a …
efficient, spiral concentrators have long played an important role in minerals processing. The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Spirals require a minimum of maintenance and upkeep, and offer a relatively simple unit operation that translates to low capital and operating cost.

Beneficiation of cassiterite ore was studied using different gravity separators like Knelson concentrator, spiral, jig, and table for the recovery of tin . Performance efficiency of jig and table for generating both high grade and recovery of tin was more than Knelson. Alternately, Knelson concentrator performed better than a spiral concentrator.
Experiments were carried out using a spiral concentrator test rig containing feed conditioner, centrifugal pump and a spiral concentrator with feed to spiral and …
Recent iron ore processing studies have shown that heavy and gangue mineral partition curves can separately provide critical information related to spiral separation efficiency Sadeghi et al ...
Spiral concentrators are used in the iron ore industry to separate heavy iron oxide carrier particles from the light silica ones. Losses of iron occur mainly in the fine (− 75 μm) and coarse (+ 600 μm) size fractions. This paper analyzes the radial distribution of iron oxide and silica particles in the reject of a 7 turn spiral.
