Flotation technology has been developed to create ideal conditions to maximize flotation performance for all roughing, cleaning and scavenging duties. The cell can be modified to handle high density slurries. DV™ flotation mechanism The latest DV™ (Deep Vane) flotation mechanism design improves air dispersion and bubble size distribution.The cell can be modified to handle high density slurries. Enhanced performance. Metso Outotec RCS™ flotation machines have made several advances in flotation design and technology. Maximize bubble-particle contact within the mechanism and the flotation tank leads to enhanced performance.
