Froth flotationWikipedia

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.

of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified. Each of these

Basic Principles & Variables Affecting Froth Flotation

The mineralogical character of the ore determines also the extent to which grinding must be carried before flotation is applied. This matter has been previously discussed. In the agitation froth process, the recoverable mineral content of an ore, the amount of a given oil necessary, the percentage of solids in the pulp treated, the grade of concentrate and the recovery attained are strictly
