The Aachen™ High Shear Reactor is designed to facilitate mass transfer by increasing the dispersion of gas in a process fluid or slurry, resulting in improved gas utilisation and efficiencies. Typical applications are the leaching of gold ores with cyanide, as well as chemical and wastewater treatment processes where large amounts of gases are required to be dissolved in fluids.

Unlike conventional mechanical and column flotation cells, Imhoflot™ is a high-intensity flotation machine including a two-staged aerator/reactor and separator. The slurry is fed to the aerator and accelerated in the venturi nozzles at a given time. At this point, the air is self-aspirating and shears into fine air bubbles. The particle and bubble attachment mainly occurs efficiently within the high-shear aerator and in the high turbulent mixing zone in the downcomer.
