During the flotation test, the froth discharged in to the continuously weighed launder, and 3 to 15 separate froth samples were continuously taken into small sampling dishes (see Figure 1). Water and solid contents of these samples were determined by drying,
Figure 2: Typical form of Grade/Recovery Curves for froth flotation 1.2 Hydrophobicity/hydrophilicity The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water-repellent (hydrophobic).
Flotation Froth. Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic).
Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Provision to remove froth by the use of froth paddles on all flotation cells should be included in the original design. The additional capital cost required for froth paddles is a reasonable investment since these devices tend to negate errors in flotation pulp level or frother addition.
