Recovery of fine coal using column flotation at Powell

In 1989 a column flotation process was developed at the CAER, which enabled the economical recovery of coal fines from high-ash fine refuse. The laboratory design was expanded to commercial scale and installed at the Mayflower Coal Preparation Plant of Powell Mountain Coal Company in December, 1989.
