    The beneficiation potential of the three ligands decreases in the order SHA > BHA > SA, as reflected by both sample grade and total rareearth oxide (REO) recovery. From an ore sample containing % rareearth oxide by weight, flotation with SHA results in the greatest total recovery of REO (%), with an increase in grade to % REO.
