The process design of gold leaching and carbon-in-pulp,

The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first,DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND,gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon-in-pulp (CIP) and the carbon-in-leach (CIL) processes, have been widely used since the 1970s. Due to the economic importance of these processes, their simulation hasACTIVATED CARBON IN GOLD RECOVERY - Kemix,Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields. The high surface area is contained in the millions of pores of varying sizes, these being

Improving the process performance of gold cyanide leaching,

In the gold mining industry today, cyanide leaching is the prevailing method for solubilizing and recovering gold. Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon (Fleming et al. 2011). Typically, the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery. TheseCarbon and Resin Technologies for Gold Recovery | SGS,,Carbon Technologies to Recover Gold CIP (Carbon-in-pulp) / CIL (Carbon-in-leach) / CIC (Carbon-in-columns) SGS metallurgists developed and continue to improve on these cost-effective, time-tested and proven processes. In each, activated carbon is used to extract gold from the cyanide leach solution.,
