These carbon recovery techniques include: Carboninpulp The ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or "pregnant" with gold. Carboninleach
Activated carbon is widely used for gold recovery from cyanide leach liquors via carboninleach (CIL) or carboninpulp (CIP) technology. From all the base metals cyanide complexes typically present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded onto activated carbon(6).
effects. Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and pregrobbing at the ore surface. A variable order empirical

Jul 21, 2016 · This invention relates to the recovery of gold from carbon fines. Carbon fines are produced when carbon, which is used in a carboninleach (CIL) or carboninpulp (CIP) process for the recovery of gold, is broken. Typically, these fines, loaded to some extent with gold, exit from a last adsorption stage of the process and are then lost.
Carbon adsorption is increasing using in newer plants for gold recovery. Carbon in Pulp (CIP) technique involves contacting the leached pulp with granular carbon in a series of agitating tanks with a sufficient retention time.

This article serves to discuss the fundamental aspects of gold recovery utilizing the CarboninPulp or CarboninLeach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as
Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until the 1970''s, with the explosion of heap leaching of vast quantities of low grade gold ores, and subsequent production of many gallons of pregnant leach solution.
CarbonInLeach (CIL) The CIL process integrates leaching and CIP into a single unit process operation, in which the leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanide solution.
