Jan 01, 2012 Froth flotation is a complex physical and chemical process influenced by multiple operational variables such as inlet air flow, froth depth and reagent addition. It is well recognized that froth visual appearance observed can characterize the combining effect of multiple process conditions on flotation, and it is also known as the indicator of

Flotation Froth an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

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.

The Vertical Froth Pumps is specifically designed to solve pumping difficulties seen with froth or a high-viscosity slurry.. Froth pumps are vertical shaft slurry pumps with integral sumps generally used on the output from froth flotation cells. Centrifugal pumps cannot pump froths, and therefore require sufficient volume in the sump to hold the froth until broken down to a liquid. The froth
