Spiral concentrators ("spirals") are commonly used to separate valuable heavy minerals from light gangue minerals by gravity. This paper examines the classification of particles as they flow down a spiral concentrator and relates the results to the number of turns. The tests show the possibility of reproducing the performance of …

This paper presents the size recovery curves of valuable and gangue minerals in industrial roughing, cleaning and re-cleaning spirals of two iron ore processing plants. The paper consists of two sections. The first section describes the operation of a spiral concentrator and recalls the concept of mineral size recovery curves.

A spiral concentrator is a gravity concentration device. It was invented by Humphreys in 1941. Firstly, it was designed and developed based on experience and by extensive testing of prototypes and modifications. The main objective of the present study is the simulation of the particulate flow of more realistic solid concentrations (i. e., 15 wt.-% …

Since the classification in a spiral concentrator depends on particle specific gravity and size, the operation of spirals can be analyzed using size recovery or partition …

Multotec has designed and optimised both single ( SX4) and double ( SX7 and MX7) coal spiral concentrators that are supplied with steel rubber-lined or PVC/polyurethane pipe launder systems. The spiral models each have different combinations and have been developed to suit the coal quality.

Gravity separation of fine heavy minerals in the size range 1.5 to 0.04 mm may be conducted on spiral concentrators. Spiral plants may consist of multiple stage spirals, depending on the mineral being recovered and the product requirements.
