• The Leachox™ Process Maelgwyn Mineral Services

    Grinding refractory gold ores to below 20 microns and finer whilst liberating more gold also liberates many other mineral species which affect the oxidative and cyanide downstream process. In many cases when only ultra fine grinding is used a maximum recovery is reached and grinding finer actually reduces the precious metal recovery.

  • The effect of grinding chemistry on cyanide leaching of

    For that reason cyanide gold leaching is very efficient when ceramic or high chromium media was used during the grinding of the ore. It can be expected that the leach behaviour would be different if leaching is preceded by pre-oxidation as is often done for pyrrhotite bearing ores.

  • Manganese Silver Ore Treatment Method911 Metallurgist

     · Excess air should be used during grinding and agitation. Gold in some manganese-silver ores is amenable to direct cyanidation and its extraction is not increased by reduction. Gold in other ores follows the silver and is more or less refractory and is benefited as much as silver by reduction.
