FLSmidth Launches 2 New Developments in Flotation

FLSmidth introduced two developments in their flotation portfolio — the WEMCO II and the REFLUX Flotation Cell (RFC) — at the recent SME Annual MINEXCHANGE 2022 SME Annual Conference & Expo in Salt Lake City, Utah.

The WEMCO II Flotation Cell builds upon the WEMCO, but with optimizations to the rotor and stator/hood that the company said greatly improves power consumption, air flow and pumping. The 40,000 WEMCO flotation machines currently installed worldwide have delivered decades of efficient recovery for customers, said the company, but the new WEMCO II’s combination of efficient aeration and optimum solids suspension increases recovery and concentrate- grade performance, as well as reducing reagent consumption.

Also getting an official launch at SME was the REFLUX Flotation Cell. The company displayed the smallest industrial- scale version of the RFC at the trade show, highlighting what it described as a ground-breaking technology that reduces plant footprint as well as water, air and energy requirements. The RFC, said the company, reduces CAPEX by 35% and with no direct power input to the RFC, this results in 60% less energy use in a flotation circuit. Results from pilot-scale studies indicate that RFC technology can help mines use up to 60% less energy in their flotation circuits. Improved kinetic efficiency also reduces the amount of water used in the recovery process.
