实验对比了熔剂中硫和镍的质量(mS和mNiO)变化对镍扣质量(mbutton)的影响,结果表明:mbutton主要受mNiO的控制,mS的变化对其影响则较小.采用X射线衍射(XRD)分析了6个不同mS、mNiO的熔剂所制备镍扣的矿物成分,结果显示:镍扣矿物成分单一,以Ni3S2为主,含少量NixS6,不含NiS、Ni3S4和NiS2等矿物.改变所加入的mS和mNiO,镍扣的矿物组成并不改变,仅是Ni3S2和NixS6相对含量发生变化.
In order to understand the influence of changing contents of nickel and sulfur on the constituents of nickel sulfide button, six buttons of different collector charge were studied. The components were further confirmed by X-ray diffraction (XRD).The experimental results show that, the weight of the of button is mainly controlled by the content of nickel, the button contains mostly Ni3S2, and some NixS6 without any minerals of NiS, Ni3S4 or NiS2. The mineral variety does not change with different contents of nickel and sulfur, only the relative percentage of Ni3S2 and NixS6 alters.
