Through the flotation process, the mineral matter is separated from the fine coal (which is smaller than 0.5 mm in size). The underflow reports to spiral separators/concentrators, which separate the lighter-density coal from the heavier-density material. The use of dewatering screens is generally the first step in the coal dewatering process.
