option is to convert coal into high quality, clean burning transportation fuel. There are two commercially demonstrated routes for converting coal to transportation fuels through gasification (Figure 1). The widely known FischerTropsch process was first discovered in the 1920s.

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