CONCLUSIONS
Metso’s latest rotor design FloatForce+ was tested in
Kennecott Copperton Concentrator in several surveys
throughout the past year. Mixing profiles, power draw and
metallurgical performance was under the evaluation com-
pared to the FloatForce rotor. Mixing profile results showed
that FloatForce+ was able to maintain as good solids sus-
pension within the cell as FloatForce with the tested tips
speeds. Power draw with both rotors were similar. It wasn’t
possible to compare the metallurgical performance of the
two rotors due to the feed variations and high sampling
errors.
