FLS forges ahead with new innovations
To get an update on its latest flotation developments , IM spoke to Dariusz Lelinski , FLS Global Product Director , Flotation and Lance Christodoulou , FLS Global Product Director – REFLUX™ Technologies . Lelinski began by putting its conventional flotation offerings in context : “ We have two main solutions today – first our well established forced air nextSTEP offering , which demonstrates significant improvement in both metallurgical performance and energy efficiency over existing forced-air designs . We have sold almost 1,000 of these cells in the last eight years .”
When installed , nextSTEP operators note a 15- 40 % reduction of power requirements and see better wear distribution for increased rotor / stator life . These findings have a strong positive impact on total cost of ownership that can benefit both new and existing installations . Wide flow jets produced by the nextSTEP rotor and the cross pattern from the patented slotted nextSTEP stator increase the probability of bubble-particle attachment . Adding slots to the stator increases recovery and boosts overall flotation efficiency . One reason for this improvement is the higher homogenised turbulence dissipation energy . When compared to other forced-air flotation designs , the nextSTEP mechanism exhibits stronger air dispersion near the rotor / stator region , higher air hold-up and a stronger pumping effect below the rotor . CFD analysis shows that the nextSTEP mechanism generates a preferred slurry flow and positive froth movement pattern near the top of the tank .
The RFC850 from FLS has now been proven at full scale at a copper mine in Poland
This improves froth mobility and recovery of coarse particles over other competitive designs .
Lelinski said in greenfield projects FLS is very busy with proposals and testwork with customers , plus helping engineering houses on
