Separation of chalcopyrite from galena with 3-amyl-4-amino-1, 2, 4-triazole-5-thione collector: Flotation behavior and mechanism
3-Amyl-4-amino-1,2,4-triazole-5-thione (AATT) reacted with Cu2+ or Pb2+ ions in aqueous solutions to form CuAATT and Pb(AATT)(2) complexes and their solubility product constants were measured as 10(-16.17) and 10(-20.60), respectively. In the moderately-alkaline media, both chalcopyrite and galena chemisorbed AATT on to their surfaces, and the adsorption amount of AATT on chalcopyrite was bigger than that on galena, which rendered a stronger hydrophobization toward chalcopyrite. While under the high-alkaline pulp, AATT only chemisorbed on chalcopyrite, not on galena. The micro-flotation findings indicated that AATT was a favorable collector for flotation enrichment of chalcopyrite and galena at pH <11.0, and realized an efficient flotation separation of chalcopyrite from galena under pH>11.5. The CuAATTcomplex was more insoluble than Pb(AATT)2, which implied a stronger affinity of AATT toward chalcopyrite than galena and returned their selective flotation separation at the high-alkaline condition.
