Cyanide Handbook Gold Ore Processing

In the process of cyanide production, the control of lime is not paid attention to, and many mines cause losses. The ore in Inner since excessive addition of lime the gold leaching rate by 5 to 10 a Shandong ore Again, a certain period due to insufficient amount of addition of lime, sodium cyanide consumption multiplied by 4. 82kg t.

  • Gold Mining Process Development Denver Mineral Engineers

    REFRACTORY ORE PROCESSING. The common definition of refractory gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.

  • Processing Technologies For Goldtelluride Ores

    To render the gold ores amenable to extraction. Usually, gold telluride ores appear to be refractory as they are always as-sociate with pyrite and other sulfides. This would lock the gold and give rise to elevated cyanide consumption. For this reason, oxidative pre-treatments are generally conducted to improve gold recoveries. Table 1.
