used grinding gold ores

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.

Gold Process MineralogySGS

gold can be recovered by conventional cyanide leaching. Refractory ores give low gold recoveries only with the use of significantly more reagents or more complex pre-treatment process. 1. Generally placers quartz vein gold ores oxidized ores and silver-rich ores are free-milling and gold can be recovered by gravity and/or direct cyanide

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
