TLDR
A comprehensive critical review of available studies on analytical and numerical modeling including computational fluid dynamics (CFD), as well as experimental approaches to determine the particle–bubble interactions in flotation cells indicates that interception collision models established based on stream functions are not applicable as they ignore the turbulence effect.About:

Surfactant-aided coal dust suppression: A review of evaluation methods and influencing factors.
TL;DR: This paper highlights the advances in the surfactant-aided coal dust suppression technology by critically reviewing prior studies and suggests more focus should be on the dynamic interaction between the coal particle and water droplet in wind tunnels or well controlled onsite conditions.
Journal ArticleDOI
A review of CFD modelling studies on the flotation process
TL;DR: A comprehensive review of the published literature regarding the computational fluid dynamics (CFD) modelling of the flotation process is presented in this paper, focusing mainly on the hydrodynamic aspect which is required for the successful operation of a flotation cell.

TL;DR: In this paper, the impact of key hydrodynamic parameters including pulp density, air flowrate and impeller speed on flotation and metallurgical responses (i.e. grade, recovery, flotation rate constant and selectivity index) was investigated.
Journal ArticleDOI
Investigation of bubble–particle attachment interaction during flotation
TL;DR: In this paper, a fundamental flotation model was used to back-calculate the induction times from the flotation experimental data, which can be used to quantify flotation performances.

The slow motion of a sphere through a viscous fluid towards a plane surface
TL;DR: In this paper, bipolar co-ordinates are employed to obtain exact solutions of the equations of slow viscous flow for the steady motion of a solid sphere towards or away from a plane surface of infinite extent.

On the collision of drops in turbulent clouds
TL;DR: In this paper, a theory of collisions between small drops in a turbulent fluid which takes into account collisions between equal drops was proposed, and it was shown that the collision rate due to the spatial variations of turbulent velocity is N = 1.30(r_1 + r_2)^2(n_1n_2)(e | v)^(1/2), valid for r_1|r_2 between one and two.
