Environmental Performance Assessment of Froth

2020-12-15  In the two stage flotation process developed at the University of Cape Town, froth flotation is used to both recover coal (stage 1) and remove pyritic sulfur (stage 2) from ultrafine coal waste, resulting in three outputs streams: a saleable coal product, a small volume sulfide-rich stream, and a reduced volume sulfide lean tailings stream.

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.

A highly efficient froth flotation procedure has been developed for harvesting algae from dilute suspensions. The method does not depend upon the addition of flotants. Harvesting is carried out in a long column containing the feed solution which is aerated from below. A stable column of foam is produced and harvested from a side arm near the top of the column.

A Review of Flotation Physical Froth Flow Modifiers

The extent of the froth phase sub-processes is dependent on two crucial froth properties: viz. froth stability and froth mobility. While it is known that froth stability depends on gas dispersion conditions, chemical conditions, and particle properties, it is also known that properties such as froth mobility can be increased by manipulating the froth zone (the compartment of the flotation cell ...
