Froth Floation Hoffman Lamson Solutions
What Is Froth Flotation? Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

2005-6-1 Defined by Finch and Dobby (1990) as “the net downward flow of water through the froth”, or by its equivalent “the net difference of water flow between the tailings and feed” (from a mass balance calculation around the collection zone), the bias can be qualitatively interpreted as the fraction of the wash-water flow used for froth cleaning. In practice, the easier-to-measure total wash-water flow rate

2020-8-15 Froth inside a flotation cell must be sufficiently stable to carry the hydrophobic particles to the lip of flotation cell for recovery. After froth being recovered into the cell launder, flotation products are normally transferred to the downstream dewatering circuit for removing the water ( Morar et al., 2006 , Wiese et al., 2011 ).
