Technical analysis of utilization of flotation tailings

The rapid development of the coal industry and increased of coal washed quantity caused more and more flotation tailings produced in China.Rational development and utilization flotation tailings have great importance of alleviating the energy shortage and the control of environment pollution.The paper introduced coal flotation processes and their characteristics in China,analyzed features of the flotation tailings treatment methods including fluidized bed combustion,coal briquetting,building materials manufacturing,gasification and pyrolysis,landfill and other methods.The paper concluded that the utilization of flotation tailings should based on economy and large-scale,and also give priority to mix combustion while develop the other utilization methods to promote the diversified development and utilization of flotation tailings.
