Abstract: Dewatering of flotation clean coal has always been the difficulty of quality management and control in coal preparation
plants. Because there are a lot of collectors and frother in flotation clean coal, it is difficult for flotation clean coal to defoaming
and pressure filtration dehydration, which directly affects the ash content and yield of the product and has a great impact on the
cost. Licun Coal Preparation Plant produces steam coal, injection coal and chemical coal of high quality, which has good economic,
social and environmental benefits.

Key words: flotation clean coal; dewatering process; quality management
