Flotation columns: getting the most from fine ores
Column flotation devices were re-introduced for mineral processing by Boutin and Wheeler in Canada in 1967, when wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product. By the late-1980s column flotation had become a proven industrial technology in the mineral industry.

Effect of pH, air velocity and frother concentration on combustible ...
The column flotation produces better separations mainly with fine particles, since it eliminates the problem of hydraulic entrainment. Column flotation creates a more quiescent environment for particle—bubble aggregates, generates small bubbles and eliminates the need for banks of conventional mechanical flotation machines [5].

Abstract Remote sensing of salinity using satellite-mounted microwave radiometers provides new perspectives for studying ocean dynamics and the global hydrological cycle. Calibration and validation of these measurements is challenging because satellite and in situ methods measure salinity differently.

NASA Salinity: SPURS
Since August 2011, NASA's satellite instruments have revealed how sea surface salinity changes over time with unprecedented detail. This new perspective of our ocean provided the scientific motivation for the Salinity Processes in the upper-Ocean Regional Study (SPURS), a coordinated field campaign to understand causes behind the patterns and variations of salinity at the ocean's surface.

A method and apparatus are disclosed for the microbubble flotation separation of very fine particles, especially coal, so as to produce a high purity and large recovery efficiently. This is accomplished through the use of a high aspect ratio flotation column, microbubbles, and a countercurrent use of wash water to gently wash the froth.
