A FINE COAL CIRCUITRY STUDY USING FLOTATION GRAVITY
The circuit arrangement that is commonly used to treat the fine coal (28 M x 0) in today's coal preparation plants utilizes coal spiral concentrators and conventional froth flotation. In this circuit, the coal spirals are used to treat the 28 x 100 mesh size fraction while the 100 x 0 mesh size fraction is treated using conventional flotation.
