A flotation column is a reactor composed mainly of a collection zone and a froth zone. The collection zone has the objective of attaching hydrophobic particles to bubbles and the froth zone is responsible for the carrying capacity and froth enrichment (Finch and Dobby, 1990, Dobby and Finch, 1991).The drop-back material from the froth returns to the collection zone, goes back to froth, in ...

With low gold grades (0.15–0.4 g t − 1 Au) and a poor liberation, this 3pc cell was able to produce a product (12% gold recovery) with the quality of a rougher flotation concentrate (13 g t − 1 Au). These results could not be attained in the conventional column cell operating under similar conditions.

Froth flotation is a process for selectively separating of 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.

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
