Flotation Machines
Laboratory flotation machines for reliable and repeatable mineral separation testing.
LAARMANN flotation machines are designed for laboratory flotation testing and the reproduction of plant-scale flotation processes. They provide precise control over important test parameters such as impeller speed and air flow, helping laboratories achieve consistent and repeatable results. Different flotation cells, impellers and optional sensors are available to suit a wide range of mineral processing applications.

Flotation Machines FAQ (Frequently Asked Questions)
A flotation machine is used to separate valuable minerals from unwanted
material by exploiting differences in their surface properties. Air bubbles
are introduced into the slurry, allowing hydrophobic mineral particles to
attach to the bubbles and rise to the surface as froth.
The LAARMANN LMFTM can be configured with interchangeable flotation cells
ranging from approximately 0.2 to 7 litres, allowing laboratories to perform
tests at different sample volumes.
Yes. The LMFTM provides digital control of important flotation parameters,
including impeller speed and air flow. Optional instruments can also be used
to monitor parameters such as pH, temperature and flotation level.
In a bottom-driven flotation machine, the impeller is positioned at the
bottom of the flotation cell. The impeller agitates the slurry and disperses
air through the cell, promoting contact between mineral particles and air
bubbles for efficient flotation and froth formation.
