spiral concentrators in mineral processing

Spiral Concentrator Multotec - Multotec Mineral

Spiral concentrators are simple low energy-consuming devices used for mineral separation mainly on the basis of density or by shape. Spirals are widely used in mineral processing as a method for pre-concentration and have proven to be metallurgically efficient and cost-effective.

A simple process control model for T spiral concentrators

2009-8-26  Large mineral processing plants consist of hundreds of spiral concen- trators, and the adjustment of splitters is time consuming, impractical and is in many cases neglected. Spiral splitter adjustment has up to now been the only means to adjust recovery into the concentrate, middling, tailings and (in some cases) the slimes streams.

Size recovery curves of minerals in industrial spirals

2014-10-15  Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992). The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001). The spirals operate on both particle size and density which make their
