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.
Froth Flotation Froth flotation is one of the most versatile and flexible of all mineral separation processes. Reasonable results are fairly easy to obtain but outstanding performance from a circuit requires constant attention and good understanding of the process and ore. Some of the variables that affect the operation and
1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air
Sep 14, 2011· Froth flotation is a three phase separation process for complex ores based on the manipulation of the difference in hydrophobicity of the solids. Suspended, hydrophobic metal-rich particles are contacted with, and subsequently combine to, air bubbles — whilst the more hydrophilic gangue particles sink and are recovered to the tails stream.
At present, the commonly used beneficiation processes include gravity separation, magnetic separation, flotation and so on. The chemical beneficiation process such as flotation process is more complicated than the physical beneficiation process su...
