Coal flotation cost

Jan 03, 2020 Following grinding, the coal was transferred to a Fagergren laboratory flotation cell and diluted to the flotation pulp density, which was normally 9.7% solids. Impeller speed was 1520 rpm and the temperature of the pulp was maintained between 24 – 26 C for all tests. The pH was maintained between 7.2 – 7.4

    When a micro-bubble flotation technique was employed to float Appalachian coal, it produced a cleaner coal product than conventional macro-bubble flotation. A general kinetic model was proposed to represent the rate of flo tation of coal. For two Appalachian coals, the model successfully represented the flotation kinetics of uniformly sized coal

    Coal flotation mainly uses the difference between the surface hydrophilicity and hydrophobicity of coal particles, caused by their interaction with reagents, which results in the separation of clean and tail coal from coal slime in the flotation machine or flotation column [1, 2]. In the flotation process, the reagent dosage is the main factor
