摘要: A novel surfactant, thiocarbonohydrazide (TCH), was synthesized and tested for the first time as a selective chalcopyrite depressant in Cu-Mo separation. Its adsorption mechanisms on were studied by flotation tests, zeta potential, FTIR, XPS ToF-SIMS measurements. FTIR potential analyses suggested that there strong chemisorption reaction between TCH chalcopyrite, resulting formation of TCH–copper complexes. measurements further confirmed onto surface showed this is due to its S N atoms, which form five-membered chelating rings releasing H ions.
