  A novel vacuum distillation method for preparing high purity antimony ...

  2022111 · A new clean process for preparing high purity antimony trisulfide directly from antimony ore by a two-step vacuum distillation method at low temperature was proposed in this study. Impurity arsenic was volatilized into the gas phase, and antimony and other impurities were retained in the residue in the first step at 773 K and 5 Pa for 60 min …

  Selection on the Process for Removing and Recovering Antimony …

  201727 · It can be seen from Eq. () that Sb 2 S 3 is deposited on the surface of gold particles, forming a dense product layer and hindering the diffusion of CN − and O 2 to the gold particles, leading to low leaching ratio [3, 4].Effect of Antimony on Pretreatment Process. The melting point of antimony compounds, generated in the roasting process of …

  Sulfur fixation and reduction roasting of stibnite for clean …

  2019121 · The direct sulfur fixation and reduction roasting of antimony sulfide (Sb 2 S 3) were investigated for antimony extraction, based on the combination of metallurgy and beneficiation.Zinc oxide (ZnO) and carbon, used as the sulfur-fixing agent and reductant, respectively, were roasted with Sb 2 S 3 to form Sb metal and zinc sulfide (ZnS). The …

  HOW TO PROCESS ANTIMONY ORE, ANTIMONY ORE …

  Only water antimony calcium, the density of the ore is 3.14g/cm3, and the ratio of the gangue is only 1.29, which belongs to the difficulty to be sorted by density, but it is not the main component in the antimony ore and does not affect the use of gravity separation.

  ANTIMONY ORE -

  RG Richards. ：. Antimony ore samples (mean assay 18. 7 per cent antimony) from Endeavour Inlet, Marlborough Sounds, New Zealand, were tested for upgrading by flotation to a saleable product ( greater than equivalent to 60 per cent antimony). The effects of activating agents, collectors, frothers, pH, conditioning time, and particle size ...

  A Review on Pyrometallurgical Extraction of …

  201628 · Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as …

  Extracting antimony from high arsenic and gold-containing stibnite ore ...

  201961 · Despite this, technical problems such as high Sb content in slag, relatively low purity of antimony trioxide (Sb 2 O 3), and large fluctuation in the concentration of SO 2 still exist. Ye et al. (2015) proposed a low-temperature molten salt smelting process that could directly produce antimony from its ore. Zinc oxide (ZnO) was added as a ...
