The Spiral Concentrator first appeared as a production unit in 1943 in the form of the Humphreys Spiral, and its first application was on chrome-bearing sands (1). Applications for the concentration of iron ore and mineral sands soon followed. By the 1950's, standard practice in the Australian Mineral Sands Industry was to use
The Spiral concentrator has performed better at feed pulp density of 30% by producing concentrate of high grade (93.5%) and with highest recoveries of 96%. The desliming of raw sand has been done using using hydrocyclone. When the deslimed feed is fed to the spiral, high concentrate grades has been produced with very high recoveries as high …
Mineral Spiral Concentrators: Multotec spiral concentrators segregate iron ore, chrome, mineral sands and other high-density mineral particles in sizes of less than 1.5 to 0.04 mm. Multotec's HX3, HX5 and SC mineral spiral concentrator ranges are comprised of modular housing frames consisting of two spiral assemblies.
Large mineral processing plants consist of thousands of spiral concentrators resulting in large plant footprints (capital intensive) and the adjustment of splitters is time consuming, impractical and is in many cases neglected-high capacity (HC) spiral concentrators aim to address these shortcomings.
The spiral models each have different combinations and have been developed to suit the coal quality. New research and development has shown that our compact, modular designs have added flexibility when building or replacing spiral plants. This results in processing solutions that extend the life of your plant and reduce overall maintenance costs.
Our FLEXSERIES modular plants offer a highly efficient, yet compact layout, utilising advanced process design methodology.With capacity from 5tph up to 250tph, each module can be customised with a circuit to suit even the most challenging ore body. Designed to accommodate Mineral Technologies' high quality spiral technology, customers can …

Chapter 1. Spiral §1. 1 Spiral A spiral concentrator uses gravity to separate particles of different densities. It is used globally in the mineral processing industry. It is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials, spirals …
The tracer particle trajectories and the free surface velocity of a spiral were determined with a high-speed camera. An increase in the flow rate leads to an increase in the liquid depth and free surface velocity along the trough surface. Three full turns of the high gravity spiral concentrator are sufficient for achieving a stabilized flow.
Spiral concentrators are gravity separators usually separating particle sizes between 0.1 and 2 mm in a water carrier medium1,2. The capacities of the spiral concentrators range between 1 and 3 t/h dry solids and recently in excess of 7 t/h in the case of high capacity spiral concentrators when treating typical heavy mineral beach …
Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …
Spiral concentrator is the key operating unit and is widely used for concentrating different minerals and coal. Normally in mineral processing a rigorous and costly experimental evaluation of laboratory and pilot-scale equipment trials are conducted for accessing the performance of any unit operation.
