WEBA technique to recover fine coal is oil agglomeration. It uses hydrocarbon oil to selectively aggregate coal particles in an aqueous suspension. If a large amount of oil is used (, 30–50% based on coal weight), relatively large agglomerates are produced, which can be recovered on a screen (Wheelock and Shen, 2003 ).
WEBOil agglomeration [1] [2] is one of the special processes of mineral processing.
