TLDR
In this article, the problem of froth flotation kinetics is treated as a transport phenomenon and two coupled equations of balance are formulated which concern the particles attached upon the bubbles and the free particles in the pulp.About:

A review of induction and attachment times of wetting thin films between air bubbles and particles and its relevance in the separation of particles by flotation
TL;DR: It is proposed that measurements of the bubble-particle attachment can be used to interpret changes in flotation behaviour or, in conjunction with other factors, such as particle size and gas dispersion, to predict flotation performance.

Stability of foams in silicate melts
TL;DR: In this paper, the authors quantify the relevant parameters and determine stable bubble size and critical film thickness in a foam as a function of melt viscosity, surface tension, and time.

Froth flotation: kinetic models based on chemical analogy
F. Hernáinz,Mónica Calero +1 more
TL;DR: In this paper, several kinetic aspects of flotation of celestite and calcite in a mechanical cell with sodium dodecylsulphate as the collector agent, using pure minerals ranging in average particle size between 137 and 74 μm, with a constant pH 3 in the flotation bath in all experiments.

Kinetics of flotation. Order of process, rate constant distribution and ultimate recovery
TL;DR: In this article, three primary parameters, namely, distribution of flotation rate constant f(K), order of the flotation process n and ultimate recovery R∞, are presented to perform analysis of the floatability distribution.
Journal ArticleDOI
Simultaneous optimization of the performance of flotation circuits and their simplification using the jumping gene adaptations of genetic algorithm
TL;DR: In this article, Mehrotra et al. used NSGA-II-mJG to optimize the performance of froth flotation circuits and obtained Pareto optimal sets of equally good (non-dominating) solutions.
