1 Froth Flotation – Fundamental Principles

2009-8-27  Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator. The air is then dispersed as bubbles through the slurry, and comes in contact with particles in the slurry that is drawn through the stator.

Flotation Machine - an overview ScienceDirect Topics

Currently, flotation-cell design is primarily a proprietary function of the various cell manufacturers. Flotation plants are built in multiple cell configurations (called banks), and the flow through various banks is adjusted in order to optimize plant recovery of the valuable as well as the valuable grade of the total recovered mass from flotation.

Flotation Circuit - an overview ScienceDirect Topics

Modern flotation machines are high-intensity equipment designed to create very small bubbles and higher flotation rates. Smaller bubbles are generated by intensive mixing of pulps with air so that fast collisions between particles and bubbles take place. Microcel machines work with forced air, whereas the Jameson cell works with induced air.

2020-11-1  The froth zone recovery was described as a function of the solids flowrate entering the froth by true flotation (S F), launder design (ξ F) and froth residence time (τ F). The effect of launder design was quantitatively represented by the mean froth transport distance in a flotation cell (Yianatos et al., 2020). (1) R F = f (S F, ξ F, τ F)

Final Master Thesis - CORE

2017-1-21  Flotation technology involves the interaction of gas to solid (bubble-particle) and gas to liquid (gas dissolving into liquid and precipitated as fine size bubbles). The amount of gas (air) dissolving into the liquid solution determines the availability of gas bubbles for interaction with the suspended particles.
