Flotation Froth an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

In mining applications, froth flotation is often used during the mineral processing stages to help separate the solids from the heavy slurries by taking advantages of differences in their hydrophobicity. The first step in the process is to gather and finely crush and grind chunks of ore into fine particles, with the goal of separating the individual minerals into their own separate grains.

Kinetics of flotation CONCENTRATION OF MINERALS

Flotation kinetics (from the Greek Kintik243;s driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, i.e. R = f (t). It allows a quantitative description of the flotation process in time.
