10.10.5. Pulp-froth multiphase model. In this approach, the recovery of particles from the flotation operation is considered with two distinct zones, namely the pulp phase and the froth phase. In the pulp phase, the particle-bubble aggregates are formed and transported to the pulp-froth interface.
This paper presents a critical literature review on modelling for froth flotation control. Models reviewed have been sub-classified as empirical, phenomenological and hybrid according to their characteristics. In particular, it is highlighted that models have so far primarily focused on the pulp phase, with the froth phase often neglected; when ...

These types of processes are consequently often controlled suboptimally owing to high personnel turnover, lack of fundamental understanding of …

The scale-up relationship was developed based on dimensionless parameters. First, a scale-up factor (ξ) was defined as the ratio between the actual flotation rate (k AC) of the collection zone in a perfectly mixed industrial cell (N = 1) and the flotation rate (k B) in a laboratory batch cell, (1) ξ = k AC k B The apparent flotation rate constant for the …

Flotation Reagents. mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses. Flotation as a concentration process has been extensively used for a number of years. However, little is known of it as an exact ...
Category: Science & Tech. flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine ...

Since the early days of flotation, process technicians have known that the speed at which the froth is recovered over the lip of the cell has a very direct and consistent influence on the grade and recovery of the circuit. No plant would deny that, even to this day, one of the most important aspects of a process technician's job is ensuring that the froth is moving …
Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.

Froth flotation represents the most versatile separation method in mineral processing. It takes advantage of the different surface minerals properties to selectively separate more hydrophobic minerals from less ones towards interactions with air bubbles. Flotation has been initially developed to treat the sulfide minerals of copper, lead, and zinc.
