Pregrobbing gold ores ScienceDirect
· In a mildly carbonaceous Carlin ore, around 70% of the gold was recovered using a CIL process in comparison with 15% gold recovery without activated carbon (Afenya, 1991). In general, utilization of anionexchange resins or granular activated carbon in cyanidation of pregrobbing ores improves the gold extraction but depends on ore mineralogy and the amount of
