Froth flotation ore dressing Britannica

water by a process called froth separation. Air is bubbled vigorously into the solution and a froth is formed. The composition of the froth differs from that of the bulk because the organic solute concentrates at the interfacial region. The froth is mechanically removed and collapsed and if

History of Flotation Patents

This is the part of the subject of which we have heard the most indeed until recently the literature of the flotation process was closely identified with the records of patent litigation. That is why the scientific principles are as yet so little understood and the technology of the process has made such scanty progress. The aim of a patent specification is to disclose just enough to prove

interesting facts of froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing paper recycling and wastewater treatment industries. Historically this was first used in the mining industry where it was one

Flotation Froth an overview ScienceDirect Topics

The most widely accepted method for upgrading ultrafine coal is froth flotation. Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent called a frother is normally added to promote the formation of

Froth Flotation Process Detailed Explanation With

Froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer.

Flotation Facts for Kids KidzSearch

Flotation is used to separate sulfide ores from the impurities in the ore ( gangue ). A detergent is added to the mixture and it is stirred. The sulfide minerals float while the gangue sinks to the bottom and is removed. This is used in making zinc where zinc sulfide ( sphalerite) is a major zinc ore.

1 Froth Flotation Fundamental Principles

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
