Evaluation of the properties of complexing agent-collectors of eudialyte flotation

Acid-based and complexing properties of reagent-collectors (carboxylic and hydroxamic acids, styrylphosphonic acid and dialkyl ether of phosphoric acid) for flotation of zirconium-containing minerals have been studied. Stability constants for zirconium compounds of investigated reagents have been determined. Eudialyte-containing ore flotation has proved high efficiency of hydroxamic acids.
