Employing sulfur–phosphorus mixed acid as a depressant: a novel investigation in flotation of collophanite
作者: Liu, Mingxia ; Zhang, Hanquan ; Yu, Hong ; Zhou, Feng ; Jin, Yanfeng ; Xiao, Linbo
Inorganic acids (sulfuric acid (H2SO4) or phosphoric acid (H3PO4)) are generally employed as depressants in the reverse flotation of collophanite to sep. apatite from dolomite.In this study, the flotation performance of a collophanite ore was studied, employing H2SO4, H3PO4, and a sulfur-phosphorus mixed acid as the depressants.The flotation tests revealed that the sulfur-phosphorus mixed acid could depress the apatite effectively.A high-quality concentrate with P2O5 content of 28.4 wt% and MgO content of 0.95 wt% was obtained, the corresponding P2O5 recovery of which was 85.0%.Furthermore, the separation mechanism of apatite and dolomite was clarified by zeta potential measurements, solution chem. anal. and XPS.Within the pH range of 4.0-7.0, the zeta potentials of apatite were neg. while those of dolomite were pos. in the presence of all the three acid-depressants.The addition of sodium oleate made the potentials of both minerals to a more neg. position.However, the potential shifts of dolomite were much more significantly neg. than apatite when H2SO4 or H3PO4 was used.It indicated a greater absorption of sodium oleate on the surface of dolomite than apatite, which contributed to a more widen hydrophobicity gap between the surfaces of apatite and dolomite.SO42- and H2PO4-, not H+ or Cl-, were founded to be the pivotal ions for depressing.XPS analyses illustrated that the simultaneous additions of H2SO4 and H3PO4 as depressants were beneficial to the formation of CaHPO4 and CaSO4 on the surface of the apatite, which were harmful for the adsorption of sodium oleate, making the depressing effect more remarkable and result in a better separation of dolomite from apatite.It performed much more efficiently in collophane ore flotation when H3PO4 and H2SO4 were used corporately as a combined depressant than when they were used sep.

High-throughput evaluation of half-metallicity of Co

MnSi Heusler alloys using composition-spread films and spin-integrated hard X-ray photoelectron spectroscopy
Article

We demonstrate high-throughput evaluation of the half-metallicity of Co2MnSi Heusler alloys by spin-integrated hard X-ray photoelectron spectroscopy (HAXPES) of composition-spread films performed with high-brilliance synchrotron radiation at NanoTerasu, which identifies the optimum composition showing the best half-metallicity. Co75-x Mn x Si25 composition-spread thin films for x = 10-40% with a thickness of 30 nm are fabricated on MgO(100) substrates using combinatorial sputtering technique. The L21-ordering and (001)-oriented epitaxial growth of Co2MnSi are confirmed by X-ray diffraction for x = 18-40%. The valence band HAXPES spectra exhibit a systematic compositional dependence and the smallest photoemission intensity at the Fermi level (E F) for a slightly Mn-rich composition of x = 27%. The density of states (DOS) for L21-ordered Co2MnSi with different Mn compositions obtained from first-principles calculation also show the smallest total DOS at E F for x = 27% because of the formation of a clear half-metallic gap in the minority spin channel and the less localized d-states in the majority spin channel, indicating the best half-metallic nature of this composition. Our experimental results demonstrate that high-throughput evaluation of half-metallicity is possible even with spin-integrated HAXPES by capturing systematic changes in the electronic structures through the measurements on the composition-spread film. Moreover, the anisotropic magnetoresistance (AMR) of the composition-spread film is measured for electric current directions along the [110] and [100] of Co2MnSi. Previous studies indicated that a larger negative AMR ratio is a signature of a higher spin polarization. The largest negative AMR ratio is observed for x = 27% for both current directions, which also supports the best half-metallicity for this off-stoichiometric composition.

Effect of the surface morphology of alkaline-earth metal oxides on the oxidative coupling of methane

Alkaline-earth metal oxides with the rocksalt structure, which are simple ionic solids, have attracted attention in attempts to gain fundamental insights into the properties of metal oxides. The surfaces of alkaline-earth metal oxides are considered promising catalysts for the oxidative coupling of methane (OCM); however, the development of such catalysts remains a central research topic. In this paper, we performed first-principles calculations to investigate the ability of four alkaline-earth metal oxides (MgO, CaO, SrO, and BaO) to catalyze the OCM. We adopted five types of surfaces of rocksalt phases as research targets: the (100), (110), stepped (100), oxygen-terminated octopolar (111), and metal-terminated octopolar (111) surfaces. We found that the formation energy of surface O vacancies is a good descriptor for the adsorption energy of a H atom and a methyl radical. The energies related to the OCM mechanism show that, compared with the most stable surface, the minor surfaces better promote the C - H bond cleavage of methane. However, as the trade-off for this advantage, the minor surfaces exhibit increased affinity for the methyl radical. On the basis of this trade-off relationship between properties, we identified several surfaces that we expect to be promising OCM catalysts. Our investigation of the temperature dependence of the Gibbs free energy indicated that, at higher temperatures, the step (100) surface exhibits properties that might benefit the OCM mechanism.
