0.053–0.15 mm mineral sand beneficiated in single stage REFLUX™ Classifier.
A range of feed rates were used from 10 to 25 t/(m2 h).
Recovery of heavy mineral (+2800 kg/m3 material) was 85% at lowest feed rate.
Unrecovered heavy mineral had low density close to the gangue value.
Recovery of zirconium component was greater than 95%.
