Uses Of Froth Flotation Reagents

Froth flotation - Wikipedia

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti…

Flotation Depressants - Mineral Processing & Metallurgy

First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color. This is because the froth is becoming purer as ...

Flotation Reagents Used To Separate Minerals

Froth Flotation Process. The use of these reagents has been extended in recent years to three- stage selective flotation. For example, ores containing the sulphide minerals of lead, zinc, and iron, can be treated to yield three successive concentrates, wherein each class of minerals is recovered separately more or less uncontaminated by the others.

Flotation Froth - an overview | ScienceDirect Topics

Since plastics are generally hydrophobic materials, froth flotation has successfully been used for the separation of plastic materials. 5,137 5 137 For example, two plastic materials which are buoyant in a specific liquid phase can be separated from one another by the addition of a wetting agent which selectively adsorbs to one of the plastics and not the other.

The effect of reagents and reagent mixtures on froth ...

Reagent usage and type of reagent are important factors in froth flotation. The recovery and purity of the final product obtained depend on various parameters such as the type and the amount of reagent, the nature and the particle size of solids, the adsorption of reagent on solid particle surface.
