Retrospective Theses and Dissertations
The heat of immersion of coal in water and various organic liquids provides a useful means for characterizing the surface of the material, while the oil-water-coal, three-phase contact angle provides a characterization of the coal surface as well as the interactions among oil, water, and coal. Such characterizations may provide an indication of how well the coal will respond to cleaning by the froth flotation and oil agglomeration methods which are controlled by the surface properties of the material;The heat of immersion of two types of coal in water and in several different organic liquids was determined with a ...
