Dorr-Oliver Flotation

• Low power consumption – Streamlined pump-action vortex profile rotor and overhung type stator are more efficient than other Forced Air flotation units.
• Non-clogging low maintenance design rotor.
• High air dispersion capability – High shear rotor–stator combination gives a wider range of airflow adjustment than competitive systems and results in greater control of the flotation process.
• Superior metallurgical performance – Intense recirculation in a well defined mixing zone multiplies the chances of contact between mineral particles and air bubbles, providing for greater mineral recoveries and higher concentrate grades.
• Easier restarting mechanism – Overhung stator design and the vortex rotor profile keeps the pumping channels free of settled solids. This makes restarts easier after unplanned shutdowns.
• Low reagent costs – Air is a natural reagent in the flotation process. Having a wide air dispersion capability permits tuning your flotation plant to the optimum value for your process.
