  • Gravity Separation and Desliming of Fine Coal: Pilot-Plant

    2019-04-12  Two pilot-scale Reflux Classifiers (600 mm × 600 mm cross-section) arranged in a cascading sequence were used to beneficiate fine -2 mm coal. The first Reflux Classifier performed a density separation that produced a coal product contaminated with fine high-ash slimes. This was then washed in the second Reflux Classifier to remove the fine clays and mineral matter.
