Flotation, floatation 1. power or ability to float buoyancy 2. a process to concentrate the valuable ore in low-grade ores. The ore is ground to a powder, mixed with water containing surface-active chemicals, and vigorously aerated. The bubbles formed trap the required ore fragments and carry them to the surface froth, which is then skimmed off.Get A Quote

A theoretical analysis was conducted to study the role of collectors and depressants in flotation, based on the extended DerjaguinLandauVerweyOverbeek DLVO theory, where the hydrophobic force is considered. The collector-coated hydrophilic particle and the depressant-coated hydrophobic particle are simplified to a sphere uniformly covered with respectively hydrophobic and.Get A Quote
Abstract. This book presents the papers given at a conference which focused on the flotation of minerals. Topics considered at the conference included the thermodynamics of flotation, comminution, coal froth flotation, recent developments in USA rare earth technology, hydrodynamics, the scale-up of flotation processes, the integration of theory and practice, and reagent control in flotation.Get A Quote

Sea water has been used in flotation plants, showing a promising way to save fresh water usage. Previous studies indicated that divalent salts in sea water played negative roles in chalcopyrite flotation, but not much work have been conducted to understand the eliminating mechanisms. This study systematically investigated the effects of divalent cations of Ca2 and Mg2 on natural flotability.Get A Quote
Since flotation is a surface area of gas driven process, the size and behavior of bubbles in both pulp and froth phases are of paramount significance. In addition, according to the penetration theory proposed by Leja and Schulman 1 , frother molecules at the gasliquid interface interact with collector molecules adsorbed on mineral particles.Get A Quote
FLOTATION MACHINES FOR THE MINING INDUSTRY Flotation machines constitute the basic equipment for useful minerals reco-very from non-ferrous ores and other raw materials by flotation.

Fundamentally, a flotation column can be regarded as a plug flow reactor, although there exists axial mixing to some degree for most flotation columns of industrial scale. In other words, the performance of a flotation column can be equivalent to that of several mechanical flotation machines in series.Get A Quote
