Froth image analysis has been considered widely in the identification of operational regimes in flotation circuits, the characterisation of froths in terms of bubble size distributions, froth stability and local froth velocity patterns, or as a basis for the development of inferential online sensors for chemical species in the froth. Relatively few studies have considered flotation froth image

OPTIMIZATION OF AIR-INJECTION SPARGERS FOR COLUMN

A mayor constraint on column flotation capacity is froth overloading. The carrying capacity of the froth depends on the bubble surface area available for bubble-particle attachment. The bubble surface area, and hence carrying capacity, can be increased by reducing the average size of bubbles for a given gas flow rate. Efficient and proper air

Differential flotation of a chalcocite-pyrite particle bed

A cylindrically shaped, 200- to 300-g bed of sulfide mineral particles was used as the working electrode in an electrochemical-flotation cell. In a pH sodium tetraborate buffer, chalcocite floated with ethylxanthate at applied potentials ⩾ − V (versus the standard hydrogen electrode); pyrite floated at potentials ⩾ V.

Froth Floation | Hoffman & Lamson Solutions

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.
