Recovery of ultra-fine (minus 200 mesh) coal can be achieved using surface chemical based techniques such as froth flotation and oil agglomeration. Column flotation technique has shown potential to produce ultra-fine clean coal with low ash at high HHV recovery. The objective of this ongoing US DOE sponsored study is to evaluate various column configuration six different types of coal to produce premium quality coal containing less than 0.6 lb/mm Btu sulfur and less than 1 lb/mm Btu ash. The other goal of the study is to produce this ultra-clean coal at a cost of about $2.50/mm Btu. Amax Research and Development Center, prime contractor on this project, and other team members selected six different coals which are low in organic sulfur and have shown potential of cleaning to low ash level. The Center for Applied Energy Research (CAER) has evaluated two different types of bubble generating systems on six different coals to produce low ash clean coal at high ({approximately}90 percent) HHV recovery.
