Floatation Article about floatation by The Free Dictionary

The floatation of oil shale from a mixture of oil shale and phosphate has shown a high recovery of oil shale in the froth since most of the phosphate has stayed in the tailing part. Similarly, floatation of oil shale in a mixture of oil shale and calcite has shown a high recovery of oil shale in the froth layer.

Flotations Article about flotations by The Free Dictionary

flotation, floatation 1. power or ability to float; buoyancy 2. a process to concentrate the valuable ore in low grade ores. The ore is ground to a powder, mixed with water containing surface active chemicals, and vigorously aerated. The bubbles formed trap the required ore fragments and carry them to the surface froth, which is then skimmed off

Principle of operation. This slurry (more properly called the pulp) of hydrophobic particles and hydrophilic particles is then introduced to tanks known as flotation cells that are aerated to produce bubbles. The hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth.

Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.
