  • Rhenium recovery from Sarcheshmeh molybdenite

    The clarified solution contained rhenium, calcium, molybdenum and copper ions Because of the high basicity of the solution due to the presence of calcium ions, the presence of iron ions in the solution was negligible, which helped the process as the removal ofDespite many metal ions including rhenium, manganese, and copper forming anionic chlorocomplexes in acidic chloride medium, molybdenum as \({\text{MoO}}{2}^{2 + }\) cation is also negligible As demonstrated in Fig 2 b, the intensity of peaks at 3,500 cm −1 decreases in the gel after adsorption, which indicates that –NH 2 groups especially play a major role in biosorption processSelectivity recovery of molybdenum(VI) from

    Rhenium stock solutions were prepared by dissolving NH 4 ReO 4 (999%) in hydrochloric acid, and molybdenum stock solutions were prepared by dissolving (NH 4) 6 Mo 7 O 24 ·4H 2 O in hydrochloric acid The concentration of Re (VII) in the (H, NH 4 )Cl medium is 5 × 10 −4 and 5 × 10 −2 mol/L for Mo (VI)Sutulov A: Molybdenum and rhenium recovery from porphyry coppers 1970, University of Concepcion, Chile, 259Google Scholar 24 Sutulov A: Copper porphyries 1975, University of Concepcion, Chile, 206Google Scholar 25 Poplavko YM, D'yakonova FF, Mel'nikova LV: Geochem Int 1984, 21 (2): 40Experimental determination of the hydrothermal

  • Molybdenite flotation from copper/molybdenum

    Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals The bulk copper/molybdenum feed generally varies from 02% Mo to 10% Mo, and with traditional reagents the singlestageIt exhibited selectivity only for Re(VII) ions evidenced by the higher value of separation factor of rhenium and molybdenum (β Re/Mo = 707–21739) in TritonX100/N235/IAA/nheptane/NaCl microemulsion The results show that it is possible to separate rhenium and molybdenum by the new microemulsion system at the better appropriate separation conditions than that of traditional extraction, especially for the liquid mixture containing high folds concentration molybdenumSelective extraction and separation of Re(VII) from
