A practical approach to plant-scale flotation optimization
SYNOPSIS. Decision-making regarding plant-scale reagent dosage regimes and air rates is a topic of ongoing investigation and high importance. The current work explains some techniques that have proven useful in deciding on plant-scale flotation operating regimes. Specific focus has been placed on the reagents: frother and depressant, as well as ...

Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement
The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.

Fine Gold Recovery by Flotation
The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was constructed.

SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

Advanced Techniques on Fine and Coarse Particle Flotation
Flotation is a method that enables the separation of hydrophobic particles with the help of air bubbles (Fig. 3 a). In flotation, the particles adhere to air bubbles depending on solid, liquid, and gas contact phases. The interaction of particles and bubbles includes collision, adhesion, and stability [ 3, 4, 5 ].

Improving flotation energy efficiency by optimizing cell hydrodynamics
3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.
