Baffled-column flotation of a coal plant fine-waste stream

A new type of flotation column was designed specifically to deal with these problems, and a column of this design was installed and tested in a coal-cleaning plant in Ohio. The feed coal tested was the plant’s tailings-thickener product. The coal was 80% −176 µm and had a heating value of 8401 Btu/lb. The coal contained 39.8% ash, as fine clay, and 2.83% total sulfur.
