Discover state-of-the-art equipment and process solutions for your fine coal circuits. The benefits and differences of two of the most common fine coal circuits in prep plants will be highlighted, spirals and froth flotation (both column and conventional) will be highlighted.  Size range applications can overlap with these technologies and they are often employed together in a fine coal circuit with spirals handling the coarser end and flotation the finer end. Thus, a circuit approach as to how -1mm fines from today’s prep plant designs are split, what effects this has on each unit operation, and how to control the clean coal refuse split from them with a multitude of operating variables will be presented.
