Title: Enhancement of surface properties for coal beneficiation

Technical Report ·
DOI:https://doi.org/10.2172/6409667· OSTI ID:6409667

The main objective of this research project is to study ways to modify surface properties of coal, pyrite and ash-forming mineral matter for beneficiation of fine coal. Since the differences in surface properties of coal and mineral matter are utilized in several oil based preparation technologies, such as: froth flotation, emulsion flotation, spherical agglomeration and liquid-liquid separation, another objective is to delineate the role of oil. The following studies are behind carried out to achieve the objectives: Investigation of the natural hydrophobicity of coal and pyrite; development and evaluation of enhanced coal hydrophobicity; development and evaluation of reagents xanthates which modulate the hydrophobicity of pyrite; and development and evaluation of emulsion processes and their underlying principles.
