Flotation cell technology and circuit design—an Anglo Platinum perspective by C.M. Rule and A.K. Anyimadu Synopsis Froth flotation is the primary mineral processing separation step employed in the beneficiation of PGM ore bodies. Anglo Platinum operates a significant portion of the total installed flotation capacity
FLSmidth is the leader in flotation technology with sound metallurgical design principles anchored in the world’s most efficient designs. We have integrated the expertise of three world leaders with the addition of Dorr-Oliver and Wemco to create the ultimate flotation technology for process specific solutions.
Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing paper recycling and wastewater treatment industries historically this was first used in the mining industry where it was one of the great enaWemco mechanical flotation cell.
Froth flotation especially in the rougher and scavenger applications: mechanically agitated cells. this includes self-aspirated cells such as the Fls Wemco as well as designs where air is fed under pressure such as the outotec tankcell . a generic illustration of a conventional cell is
Induced gas flotation IGF and hydraulic dissolved gas flotation DGF cells have been used for residual oil removal from produced water since the late 1960’s Sport 1970; Bassett 1971. Mechanical IGF cells developed from the WEMCO multi-cell rectangular-shaped
Insight into the inner working of the Wemco flotation machine such as air dispersion turbulence levels separation zones and solids concentration. Design changes to the rotor disperser hood and geometrical lay-out produced a marked improvement in flotation conditions. It also supported certain dimensionless numbers measured in full scale ...
Jan 01 1981 However in the case of the Wemco cell the values of a and kLa are about 50 - 100 higher than those from other contactors. 0 The comparison of the performance of o Denver-type flotation cells with gas-inducing types of agitated contactors is shown in Fig. 11.
Most of the industrial flotation machines used in the coal industry are mechanical conventional cells. These machines consist of a series of agitated tanks usually 4–8 cells through which fine coal slurry is passed. The agitators are used to ensure that larger particles are kept in suspension and to disperse air that enters down through the rotating shaft assembly Fig. 11.13.
No flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. 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.
Of mechanical flotation cells in the industry include Denver equipment Galigher Wemco Outokumpu and Sala. Denver type flotation machines are also being manufactured indigenously in India. In a pneumatic cell suspension of solid particles in water is achieved by the compressed air being suitably dispersed throughout the volume of the cell.
Power requirements of the WEMCO ISF system are very low; a simple recirculating pump provides gas induction and mixing in the flotation cells. WEMCO ISF. Hydraulically induced gas flotation system. The Schlumberger WEMCO ISF unit is a compact lightweight solution for removing oil and suspended solids from produced water and wastewater.
Row consisted of five 257m3 Wemco flotation machines. The bulk concentrate stream was combined and pumped to the bulk cleaner circuit via an intermediary regrind step. The effect of absorbed power on recovery was tested by varying the rotor speed on the final scavenger cell in the five-cell row and measuring the additional copper and ...

SF Flotation Cell Features 1. Large suction capacity lower power consumption 2. Each cell has the capacity to suck air and slurry automatically 3. Lower rotational speed of impeller long service time 4. Slurry in flotation cell cycled up and down in fixed way which is favorable to the suspension of coarse particles Technical Specification
Slurry to disperse bubbles into the cell. In a column cell the flotation feed enters near the top of the cell and bubbles are generated through an external or internal sparging system Kawatra 2011. Other than the physical design differences the column cell and conventional mechanical
Tank cell flotation cells scale-up from 60–620 m3 in 1960s–now; The new flotation force impeller was developed Outotec company DorroliverWemco flotation cells scale up to 660 m3300 m3. The next step impeller and stator was developed FLSmidth company KFYJJF flotation cells scale up to 680 m3320 m3 from 1990–2018.
The flotation cell has undergone a number of changes since the process was first introduced in Broken Hill in the early years of this century. The development of the mechanical flotation cell is reviewed followed by a discussion of more recent developments such as the flotation column the air-sparged hydrocyclone the Wemco-Leeds cell the Bahr...
Using column flotation it was possible replace the rougher and two to three cleaner stages with a single column producing final concentrate. The total number of flotation cells was reduced from 64 - 300 ft3 Wemco cells to 6 - 3m x 4.5m rectangular column cells. Recirculating loads were reduced allowing an increased feed rate to the concentrator.
WEMCO SmartCell™ Flotation Wemco has long been a trusted and proven leader in flotation technology under the FLSmidth Dorr-Oliver Eimco brand. The SmartCell Flotation series combines the proven Wemco mechanism with cylindrical cells to optimize energy input aeration and mixing. This configuration reduces pulp
WEMCO 11 Flotation cells are commonly used in coarse float applications such as phosphate and potash with feeds of up to 85 plus 65 mesh an maximum particle sizes as large as 10 - 12 mesh. Flexible Modular Tank and Box Design The basic module of the WEMCO 11 Flotation system is a cell consisting of a single tank and mechanism.
