Increase Spiral Circuits Efficiency & Recovery

Sep 20, 2017· However, this would, at a minimum, increase the spiral load and, in turn, would increase the separating gravity. The secondary spiral middlings represents about 10 % of the primary spiral feed but compounds heavily in a recirculating loop. Test work has been conducted around a two-stage spiral …

Spiral Concentrator | High Performance Gravity ...

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.

Humphreys Spiral Concentrator

Humphreys Spiral Concentration of Iron OreThe Cleveland-Cliffs Iron Company PlantSpiral Plant Operation and PerformanceSpiral ConcentrationThe installation in 1948 of a Humphreys spiral concentrator section at the Hill-Trumbull plant of The Cleveland-Cliffs Iron Co. is the latest commercial method on the Mesabi Range being used for the recovery of fine iron ore. In two stages of concentration 84 spirals treat approximately 120 long tons per hour of minus 1/8 in. ore. These spirals augment the production of the heavy-density plant which recovers the plus 1/8 in. iron from the plant crude ore. Structure of the ore is such that, when crushed, …

Gravity Spiral Concentrator Working Principle

Mar 26, 2016· In a test at CSMRI, a new Mark VII Reichert spiral recovered 91.3% of the free gold contained in the feed in a concentrate representing only 5.4% of the feed weight. The unit showed little decrease in gold recovery efficiency with material down to 325 mesh (45 microns) (Spiller, 1983).
