Flotation in coal plant

Sep 29, 2003 Abstract. Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process

    Coal flotation circuits for tlIch separations are becoming more important in the processing 411=:-690/AID : (-28 mesh) coal (Miller, Podgursky, and Aikman, Aplan. 1979; and Burger. 1980). For example in the US in ,81 flotation plants processed 24 kt/d (26.500 tpd); whereas ~980, there were 80 flotation plants which processed 71 kt/d

    In coal preparation plants using flotation, approximately 5-15% of the raw coal feed is processed through the flotation unit for recovery of fine coal particles. Virtually the entire free-world supply of copper, lead, zinc, and silver is recovered in the froth of flotation machines. As the grade

    Abstract. Coal flotation of fine material has both economical and environmental benefits by recovering as much coal as possible from run-of-mine coal and by reducing air and water pollution due to the elimination of sulfur from clean coal and reduction in the solid amount which goes into the stream or in recirculating plant water

    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)

    Flotation is a complex multifaceted process that can be separated into three main areas: the coal, the chemistry and the machine, as shown in Figure 1. To solve plant issues it is important to understand how different factors within these areas affect and control flotation performance for a particular system. Factors within the coal and
