A system and method is provided for beneficiating, or "cleaning", ultra-fine raw coal with spiral concentrators. The inventive system includes multiple pre- and post-classification systems to size the finer sized raw mineral to develop a pre-sized mineral fraction within a first size range (approximately 0.15 mm by 0.044 mm). The pre-sized mineral fraction is …

 · Evaluation Of Ultrafine Spiral Concentrators For Coal. 2007; benasa, 2007, and mathew et al., 2008), spiral concentrators have the ability to achieve effective separations for particle size fraction of less than 150 m down to 45 m. the objective of this study is to evaluate the effectiveness of inplant ultrafine spiral concentrators for cleaning …

 · The clean coal streams from both spirals are combined to produce an overall clean product, while both reject streams are discarded. The circuit is normally configured so that no cleaner middlings are produced and no products are recycled. Surprisingly, circuit analysis indicates that this configuration is no more efficient than a single-stage unit.

Coal/Mica Spiral Spiral Concentrators Larger diameter units than the mineral-spiral series, these spirals are designed to take advantage of the particle shape differences. Take-off splitters at different points down the helix give this spiral a high capacity to remove refuse or siliceous contaminants from the coal or the mica.

 · Spiral concentrators are used for a number of mineral processing applications. They're extensively used to process heavy mineral sand deposits, including monazite, zircon, ilmenite and rutile deposits.
