Mine show that the flotation separation of Cu/Fe sulfide minerals is achieved at pH value about 13 for sodium butyl xanthate (SBX) and pH value around 10.5 for combined collectors ethoxylcarbonyl... of the adsorption of butyl ethoxycarbonyl thiourea on chalcopyrite[J]. International Journal of Mineral Processing, 1998, 54(3/4): 147?163. [7] FAIRTHORNE G, FORNASIERO D, RALSTON J. Formation......
] reported that sodium glycerine-xanthate (SGX) exhibits strong depressing reaction on the flotation of arsenopyrite and weak depressing reaction on marmatite with butyl-xanthate as the collector, and the infrared spectrum analysis showed that there are some -OH and -CSS- in sodium glycerine-xanthate molecule, which competes with butyl-xanthate on the mineral surface. NAGARAJ[2] revealed......
by drying in air. To prepare the photopolymer for single-photon holographic fabrication, a 5 g urethane acrylate (Sarto-mer Co. Product No: CN 965) and 1 g poly (styrene-co-acrylonitrile) (AlDRICH Co..., a mixture of 2.5 g oligomer (urethane acrylate : Sartomer Product No. CN 965) and 0.01 g initiator was added to 10 mL of the solution.
