A kinetic model for batch coal flotation

Minerals Engineering, 1989
Abstract Experiments were carried out in a batch flotation cell using four coals at different levels of variables. From the results of these experiments, it is verified that the recoveries of non-ash and ash material from any size fraction follow first order kinetics given by the equation: R = R −8 (1 − e − kt ) It has ...

In-line static mixer rapid flotation system for improved flotation kinetics

Mining, Metallurgy & Exploration, 1993
The US Bureau of Mines investigated rapid froth flotation through more efficient bubble-particle collisions that improved the overall flotation kinetics. An in-line static mixer efficiently mixed the bubbles, water and ore, selectively attaching these bubbles to the hydrophobic mineral’s surface.

Influence of flotation cell hydrodynamics on the flotation kinetics and scale up of flotation recovery

2012
Flotation is a physicochemical process and its success is governed by a number of factors; including the ore mineral association and particle size distribution, the pulp chemistry, as well as the hydrodynamics and gas dispersion of flotation machines. Due to the interactions occurring, it is difficult to characterize the effect of a specific factor and
