Recovery Of Gold From Graphite Carbon. Carbon Adsorption In Recovery Of Gold Mine Engineer.Com. The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.

Preg-robbing gold ores ScienceDirect

2005-1-1  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 anion-exchange resins or granular activated carbon in cyanidation of preg-robbing ores improves the gold extraction but depends on ore mineralogy and the amount of adsorbents added.
