Froth flotation - Wikipedia

Mar 04, 2005  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.

for froth formation. As fallowed, the flotation froth is a three-phase system. The frother concentrates at the interface of water and air bubbles, forming an envelope around the bubbles, which prevents them from colliding or touching. Frothers also lower the surface tension of the water. The forces created around the air bubble in the presence of a

Froth Flotation Process - Detailed Explanation With ...

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by ...

1. Froth Carry Rate (FCR) Is defined as the amount of dry concentrate (tonne) trans-ported by the froth over a specific surface area (m2) in a given time frame (hours), giving us the units (t/m2h). In the table below, you can see the “rules-of-thumb” for froth carry rates of different flotation duties i.e. the rougher, scavenger and cleaner.
