    The dominant type of cleaning equipment used in the plant was the dense medium cyclone (DMC). Hydrocyclones and concentrating (Deister) tables were used to reclean fine coal from the underflow of the fine-coal, low-gravity DMC circuit. Thickeners were used to close the water circuit and to help recover fine and very fine coal.

    The remaining fine coal circuit is less loaded and more efficient. Additionally, the SCI bowl effluent is generally >90% minus 10 micron and typically higher in fine silicate and clay content. The SCI unit therefore upgrades the product quality of the ultra-fines recovered.

    Research conducted at Southern Illinois University at Carbondale over the past two years has identified highly efficient methods for treating fine coal (i.e., -28 mesh). In this study, a circuit comprised of the three advanced fine coal cleaning technologies is being tested in an operating preparation plant to evaluate circuit performance and to compare the performance with the current ...

    The traditional design of a fine coal (-28 mesh x 0) recovery circuit in a coal preparation plant needs to be re-evaluated. In most prep plants the fine coal recovery circuits appear to have been added with insufficient regard given to determining the best method available for recovery of the fine coal.
