  • Preparation and Transportation of Coal

    washing—normally using jig and dense medium for coarse coal, and flotation for fine coal. Transport of coal from mines or preparation plants to consumers is also very important for the coal cost and environment. The main methods of inland transporting of coal are rail, road, barge or other water transport, slurry pipeline and conveyor. Ocean transportation is carried out by barges or ships

  • Impact of Saline Water on Coal Flotation - ACARP

    Social and commercial requirements mean that many coal preparation plants will be forced to use saline water accumulated from the associated mining operations. This investigation has identified potential opportunities to decrease the use of collector/frother in the flotation circuit by proactive use of a saline water mixture to optimise a flotation response, especially where divalent cations

  • Physical and chemical interactions in coal

    29.09.2003· 1. Introduction. Conventional froth flotation for fine coal cleaning suffers mainly from two problems: (i) a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth, and (ii) low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particles.

  • Physical and chemical interactions in coal

    29.09.2003· 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.

  • DESIGN AND PERFORMANCE ASPECTS OF COAL FLOTATION

    In coal flotation, fine bubbles also improve separation as they intensify the difference in the kinetics of the coal from non-coal particles, thus allowing concentrates with lower ash content to be produced without loss in yield.
