The flotation equipment with a downcomer such as the Jameson Cell has proven a significantly reduced residence time compared to conventional flotation cells (Harbort et al., 2003a). This design also increases the throughput through a reduced residence time while maintaining a small footprint ( Lawson, 2016 ).

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

The recent trend of installing flotation cells with volumes as large as 200 m3 in concentrators is driven mainly by economic considerations such as lower capital, operating and maintenance costs.

Combining the benefits of circular cells with the unique features of the patented DV™mechanism, the RCS™ (Reactor Cell System) flotation technology has been developed to create ideal conditions to maximize flotation performance for all roughing, cleaning and scavenging duties. The cell can be modified to handle high density slurries.

Laboratory-scale results show that both the mechanical flotation machine and flotation column as re-cleaning flotation devices could produce the clean coal with qualified ash content. However, the yield obtained by the flotation column (84.49%) is significantly higher than that obtained by the mechanical flotation cell (68.21%).

Combining the benefits of circular cells with the unique features of the patented DV™mechanism, the RCS™ (Reactor Cell System) flotation technology has been …

Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con-ventional cells; (ii) energy-intensive pneumatic cells; (iii) column cells; …

Mechanical cells have seen an exponential increase in size over the past 60 years. However, a possible size limitation due to carrying capacity constraints has been raised. Taking a Cu porphyry case, a cell sizing exercise is used to show that possible size limitation due to carrying capacity can be tested using available techniques. A range of …

Mineral carrying rates across the pulp-froth interface in the range of 1.4-3.2 tph/m 2 and bubble surface coverage between 7 and 22 %, have been determined in large rougher flotation cells (100 ...

Darabi et al. [24] investigated the influence of cell geometry on the flow pattern and turbulence characteristics in a lab-scale Denver flotation machine based on the high-speed stereo-PIV technique.

Mechanical, column, and pneumatic flotation cells (Jameson, Imhoflot TM and Reflux TM flotation cells); Impact of operation parameters on designing flotation cells (gas hold-up, superficial gas velocity, bubble size distribution and orifice type, etc.); Measurement and modelling of slurry residence time in flotation cell/circuits. Dr. Fardis ...
