US20140238906A1 - Automated system for coal spiral - Google .

Spiral concentrators have been utilized in the mineral industry for treatment of chrome-bearing sands since the 1940's. In the 1950's it was demonstrated that reasonable separation between low ash clean coal and high ash mineral matter could be achieved using coal spirals. Coal spirals are widely used in coal preparation.
