  • Study on Kinetic Modelling for Fine Coal Flotation

    Results show that the main gangue mineral in the fine coal is kaolinite. The middle density fraction of 1.40–1.60 g/cm 3 has a high yield, which indicates that the coal sample is not easy to separate. The k value can reflect the floatability. During the flotation process, the k value decreases, and the floatability worsens. The experimentalCoal surface control for advanced fine coal flotation,Investigation of mechanisms for the control of coal and pyrite surfaces prior to fine coal flotation is an important aspect of the project objectives. Large quantities of coal samples have been procured from six major seams. Samples of the same coals are also to be supplied to the University of Pittsburgh for selective agglomeration research.

  • DESIGN AND PERFORMANCE ASPECTS OF COAL

    Flotation is commonly used to treat fine coal (typically below 500 microns in size) and is a complex, three-phase process that is controlled by factors which can be divided into three facets: coal, chemistry and machine. It is most often used for treating metallurgical coal fines where the value of the product can justify the addedCoal surface control for advanced fine coal flotation,Investigation of mechanisms for the control of coal and pyrite surfaces prior to fine coal flotation is an important aspect of the project objectives.
