    Coal flotation as a rate process - Mining, Metallurgy

    Coal flotation is found to follow a first order process with the coal floating much faster than either pyrite or ash. This circumstance may be used to achieve gangue rejection during flotation. When floated with MIBC, cresol, or pine oil frothers, coal floats in the size sequence: 208 m (−65 mesh), 589 208 m (28 65 mesh), and 1.17

    The behavior of coal in the flotation process is determined not only by a coal’s natural floatability (hydrophobicity), but also by the acquired floatability resulting from the use of flotation reagents. The general classification of the reagents for coal flotation is shown in Table 12.1 (Laskowski, 2001)

    Aug 28, 2013 Froth flotation is a widely used, cost effective particle separation process. However, its high performance is limited to a narrow particle size range, e.g., between 50 m and 600 m for coal and between 10 m and 100 m for minerals. Outside this range, the efficiency of froth flotation decreases significantly, especially for difficult-to-float particles of weak

    In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
