flotation separation process brief description

Flotation separation of valuable minerals - BOC Gases ...

A process for separating minerals of different mineralogical character. A milled slurry or flotation concentrate is subjected to a first conditioning step (20) followed by a first flotation step (30) followed by a second conditioning step (50) followed by a second flotation step (60).One of the conditioning steps is with an oxidising gas, the other of the conditioning steps being with a non ...

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.

2009-1-10  The equilibrium concentration represents the maximum extent a separation process can reach. The thermodynamic basis for achieving separation is that all matters in nature have the tendency to reach equilibrium. The driving force for separation of a component from the original mixture to another phase is the difference between the initial/actual

A review of froth flotation control - ScienceDirect

2011-9-14  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.
