  • Pretreatment Process on Refractory Gold Ores with As

    Gold ores are considered refractory if gold extractions from a conventional cyanidation process are less than 80% even after fine grinding. 1) Arsenicbearing refractory gold ore has stones extremely difficult to deal with. In the stones, gold is locked up in arsenic mineral matrix as the form of microscopic or submicroscopic lattice.

  • Gold Ore Processing

    Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high gold recovery (>90%) during cyanide leaching. Gold roasting is typically a metallurgical fluidized bed process.
