    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

    A number of flotation methods are distinguished on the basis of the nature and method of the formation of the phase interface (water-oil-gas) to which the separated components are to adhere. The first method proposed was bulk-oil flotation, for which W. Haynes (Great Britain) received a patent in 1860. When finely crushed ores are mixed with oil and water, sulfide minerals are selectively ...

  • 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 removed, while the particles that remain completely wetted stay in the liquid phase. Froth flotation can be ...
