metallurgical coal production is lowering the separation density of the fine circuit. Water-only cyclones provide a low density cut but tend to lose coal. Spirals tend to ensure 100% coal recovery but have a high density cut. Combining the two units provides an efficient low density separation. 0 20 40 60 80 100 1 1.2 1.4 1.6 1.8 2 2.2 2.4 2.6
