  • Pregrobbing gold ores

     ·  · The results showed gold in the CIL residue since the chlorination process did not completely passivate the carbonaceous matter, resulting in some gold pregrobbing after cyanidation. In the thiosulfate residue, on the other hand, pregrobbed gold was not significant. The thiosulfate leach process did not suffer from pregrobbing effects. The reasons for the very low loading of gold .
