  Selective alkaline leaching of antimony from Low-grade refractory gold ...

  To eliminate the adverse effect of antimony on extracting of gold in matte smelting process from Sb-bearing refractory gold ores, the sodium sulfide leaching method was proposed to selectively remove antimony in advance. On the basis of the analysis and characterization of raw materials (XRD, SEM-EDS, mineralogical phase analysis, etc.), it can be detected …

  Recovery of gold from sulfide refractory gold ore: Oxidation …

  202141 · Sulfide gold ores account for a large proportion of refractory gold ores, therefore, it is very meaningful to recover gold from sulfide gold ores (Ubaldini and Vegliò, 2000, Saba, 2011, Hammerschmidt, 2016). Moreover, the major gold leaching process for extracting gold from ores and concentrates is still cyanide leaching.
