Froth flotation - Wikipedia

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.

Smart-Level ® Froth

The smart-level® froth measures the conductivity along its length when in a liquid, froth, pulp, slurry or emulsion. Measurements are made rapidly at 5 mm intervals along typical lengths from 500 mm up to 2 m. The smart-level® froth 500 is designed for measurements over a 0 to 500 mm range.
