Froth Viscosity Flotation Efficiency Relationship

03/08/2018  Froth Viscosity Flotation Efficiency Relationship. Post navigation. Previous. Next. Flotation efficiency is governed by the wettability of the solid as well as the surface tension at the liquid/gas interface. Both these properties in turn determine the frothing characteristics encountered in a flotation process. A number of studies have focussed on the correlation between wettability as ...

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 ...

Froth Floation Hoffman Lamson Solutions

Froth flotation efficiency is determined by a series of probabilities like those of particle-bubble contact, particle bubble attachment, transport between the pulp and the froth, and froth collection into the product launder. In a conventional mechanically-agitated cell, the volume occupied by air bubbles is low (5-10%), and the bubble size is usually greater than 1 mm. This results in a ...

Correlation between froth viscosity and flotation efficiency

01/05/1993  Higher froth viscosity, on the other hand, can retard the drainage of physically carried over, hydrophobic particles. In phosphate flotation tests, a direct correlation was observed between froth viscosity and recovery, and an inverse correlation existed between froth viscosity and grade.

Beneficiation of Fine Coal: Froth Flotation Efficiency

The only froth flotation plant currently processing fine coal (nominally minus 2 mm in this case) is the one at Tsikondeni Colliery, where a coking coal is produced. The efficiency of this plant was determined from samples of feed, product and tailings provided by the mine so as to be able to compare the efficiency with that of spirals.
