where WI v —crushing work index (kWh/Mg); E j v —specific energy of crushing (kWh/Mg); D 80, d 80 —control grain size for the feed and the crushing product, respectively (μm). By analogy with the comminution process, the smaller the pieces after the material crushing, the more energy is required for the hammering process.
Coal recovered by froth flotation allowed the recovery of more than 60% of the residual coal in the CMWR. The characterization results indicate that very fine coal (D 90 < 52 μm), composed of very low amount of ash and sulfur, provides a high gross calorific value greater than 13 500 BTU/lb. Table 3.
