WEMCO Flotation Machines

The WEMCO® flotation machines feature a unique design that is demonstrably superior to other mechanical flotation systems

Wemco Flotation Cells
  • WEMCO SmartCell flotation machines
  • WEMCO 1+1 flotation cells

WEMCO Naturally-Aspirated Flotation Cells

Its massive cast-iron bearing housing maintains accurate shaft alignment under all loads and moments, ensuring long service life. Induced air flow provides sufficient aeration, mechanical simplicity and capital economy. Like the 1 + 1® flotation machine, the SmartCell™ flotation machine can be serviced on-line and restarted easily under full load.

Features & Benefits

  • Cylindrical Tanks
  • Froth Crowders
  • Automatic Air Control
  • Ultrasonic Pulp Level Sensing
  • Froth Flow Measurement
  • Sizes 5m to 300m3


In direct comparisons by major mining companies, Wemco 1+1 cells have repeatedly delivered higher recovery and grade with easier start-up, simpler operation, lower reagent consumption, longer mechanism life and less required maintenance.

At the heart of each WEMCO 1+1® cell is a patented rotor-disperser that delivers intense mixing and aeration. Ambient air is drawn into the cell and uniformly distributed throughout the pulp, providing optimum air/particle contact. In larder cells, a false bottom and draft tube channel slurry flow, ensuring high recirculation and eliminating sanding. The combination of efficient aeration and optimum solids suspension give Wemco 1+1 cells the highest specie recovery and concentrate grade performance available, and reduced reagent consumption.


  • Self-Induced Aeration
