"Coal cleaning by froth flotation " by Choon Han

The order of addition of flotation reagents appeared very important for achieving a high recovery of Iowa coal;Appalachian coals floated rapidly with only a frother (methyl isobutyl carbinol) or an alkaline solution. A small amount of an oily collector increased the recovery of Appalachian coals significantly.

Froth Washing in Mechanical Flotation Machines

2017-10-25  Froth washing in mechanical flotation cells improves metallurgical performance for two reasons. First, wash water increases water drainage between bubbles and washes out hydraulically and mechanically entrained/entrapped gangue particles. Second, wash water breaks bubbles in the top froth layer causing them to shower their load on to the bubbles below.
