A study of particle separation in a spiral concentrator ...

Keywords Spiral gravity separation performance curves Reichert coal INTRODUCTION Among the gravity separators the spiral concentrator is perhaps one of the most efficient and simple. Its relative simplicity and high efficiency compared to other gravity separators led to its widespread use under a variety of circuit configurations.

Spiral Concentrator - Metso Outotec

Outotec spiral concentrators are used in most applications particularly for concentrating low-grade ores. Manufactured from lightweight corrosion and abrasion-resistant materials our spirals require minimal maintenance and upkeep. Gives you an effective and low-cost solution for gravity separation. Reduces maintenance with a durable design.

In the 1960’s they tended to be superceded by the use of Reichert cones. To treat 100 tph of feed spiral requirements are 48 starts of F.G.L. spirals as roughers 16 starts for middlings treatment and 8 starts of C.C.M. 2 spirals for cleaning. Indicated overall performance is 95% recovery to a grade of 95% heavy mineral.

Gravity Concentrators | Mineral Processing Research Group ...

The Knelson Concentrator takes advantage of the difference in specific gravity between gold and gangue minerals to realize a separation. The centrifugal force magnifies the difference in specific gravity and the rotor geometry facilitates retention of gold particles in preference to low SG particles that are rejected with the process rotor.

Gravity Spiral Concentrator Working Principle

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).

Spiral (Concentrators) - an overview | ScienceDirect Topics

15.5.3 Spiral Concentrator. The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral for the separation of chrome-bearing sands in Oregon. By the 1950’s spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry.

Continuous Gravity Concentrator – enhanced mineral separation ...

The continuous gravity concentrator uses similar principles of mineral separation and recovery to that of the Knelson Batch Gravity Concentrator. However the continuous technology differs by delivering a continuous stream of concentrate based on under defined settings.
