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

WORLD LEADER IN ADVANCED FLOTATION TECHNOLOGY

2019-10-11 Flotation columns derive their name from the geometric shape of the vessel. Unlike conventional mechanical cells, column cells are tall vessels ranging in height from 25 feet (7.6m) to more than 50 feet (15.2m). The surface area of a column cell is smaller than that of a mechanical cell which helps to promote a stable and deep froth.
