Extracting Gold By Carbon In Pulp with Activated Carbon ...

Carbon is very actively used in the process of recovery of dissolved gold, either by introducing direct to the CIL (carbon-in-leach) or CIP (carbon-in-pulp) tanks after leaching. Activated carbon adsorbs dissolved gold from gold leach pulp complex to be absorbed through the pores of the carbon .

Carbon Adsorption In Recovery Of Gold - Mine …

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. If the ore is a high grade, it may be feasible to tank leach it. By high grade, it would probably be ...

Elution and Carbon Reactivation - Resource book

The gold can then be removed from the solution by electrowinning onto steel wool cathodes (refer 'Electrowinning and Smelting' module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence gold adsorbing efficiency and capacity, of carbon. Carbon is only ...
