Principles of flotation Henan Deya Machinery Co., Ltd.

03/06/2012 Principles of flotation Flotation is a physico-chemical separation process that utilises the difference in surface properties of the valuable minerals and the unwanted gangue minerals. The theory of froth flotation is complex, involving three phases (solids, water, and froth) with many subprocesses and interactions, and is not completely understood.

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 removed, while the particles that remain completely wetted stay

What is the principle of floatation BYJUS

The principle of floatation states that when an object floats on a liquid the buoyant force that acts on the object is equal to the weight of the object. Following are the pointers to remember in floatation: The displaced volume of fluid is equal to the volume of the object which is immersed in the fluid. If the weight of the object is greater

PRINCIPLES OF FLOTATION Froth flotation utilises the differences in physico-chemical surface properties of various minerals. After treatment with reagents, such differences in surface properties between the minerals within the flotation pulp become apparent and, for flotation to take place, an air bubble must be able to attach itself to a particle, and lift it to the water surface (Fig. 9.1

PHYSICS : THE LAW OF FLOATATION

THE LAW OF FLOATATION. The law of floatation states that, a floating body displaces its own weight of the fluid in which it floats. This means if a log of 200kg (2000N) floats in water displaces 200kg (2000N) of water, if the same log is placed in other liquid and be able to float

Archimedes' principle

An object which tends to float requires a tension restraint force T in order to remain fully submerged. An object which tends to sink will eventually have a normal force of constraint N exerted upon it by the solid floor. The constraint force can be tension in a spring scale measuring its weight in the fluid, and is how apparent weight is defined. If the object would otherwise float, the

Jameson cell

Operating principles. Froth flotation is achieved by mixing chemicals known as collectors with the ore slurry. The collectors adsorb onto the surfaces of the particles of select minerals (usually the valuable mineral that is targeted for concentration), making these minerals hydrophobic. Air is passed through the slurry in a tank known as a flotation cell. The air is broken into tiny bubbles
