activated carbon has been the dominant process for 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
PDF | This article focuses on the use of a model in combination with economic analysis to extract maximum value out of current gold operations without the need for additional capital Two South African case studies (CIP and CIL) are presented to show that an optimum point of
Cyanidation ---carbon adsorption process is the most widely used in gold cyanide extraction process The principle in brief is the carbon could adsorb liquid gold from cyanide solution In 1970s with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold make recycle the carbon

Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore By cyaniding and carbon leaching the gold ore slurry simultaneously CIL process lower the gold mining operation cost and increase gold recovery rate to a ratio of 98%
This process is very similar to the CIP process The main differences lie in the preparation of the slurry and method for removing the gold from the leachate In a CIL process the carbon is mixed with the leachate solution not with pulp This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process
This stream is treated by the conventional CIL process which is the treatment process that has been used for the past 30 years with an extraction efficiency of 39% to 40% The concentrate stream is subjected to the new fine-grind process which research and development has demonstrated is more efficient in recovering the gold
The APT TriTank is available as a small scale CIP/CIL cyanidation plant The TriTank takes on a whole new revolutionary design making for a more environmentally conscious and even better way of using cyanidation as a gold extraction process even at such a small scale The design has multiple benefi
CIP and CIL circuits represent the primary gold process and as such their efficiencies have significant impact on your overall plant efficiency A comprehensive CIP and CIL modelling program from SGS can help you develop a TESTING (LEACH AND ADSORPTION KINETIC TESTS) The SGS approach to CIP and CIL modelling involves conducting batch gold
4-1-2017-Shared By HOT Mining Metal recovery or concentration by adsorption on activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurry The continuous processes of gold recovery by adsorption on
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold The Miller process is rapid and simple but it produces gold of only about 99 5 percent purity The Wohlwill process increases purity to about 99 99 percent by electrolysis
the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism which is a chemical occurrence Factors that affect the adsorption of gold are discussed Finally performance monitoring methods that help control the operation of the CIP/CIL process are discussed 2
Introduction of CIL process 1 Application of CIL Process CIL is developed based on all-slime cyaniding followed by Zinc replacement including thickening before leaching leaching and adsorption desorption of gold-loaded carbon and electrode-position acid-washing and thermal regeneration gold
The APT TriTank is available as a small scale CIP/CIL cyanidation plant The TriTank takes on a whole new revolutionary design making for a more environmentally conscious and even better way of using cyanidation as a gold extraction process even at such a small scale The design has multiple benefi

Carbon-in leach (CIL) is a simultaneous leach and absorption process The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon These reduce the gold yield by attracting gold meant for the activated carbon
The gold extraction was 98 % (in solution) after only 4 h and remained at this level till 48 h (related to the residue) This demonstrates that active carbon does not have any detrimental effect on the CIL process if Degussa's cyanidation process is applied
In the CIL circuit cyanide and oxygen are added to the slurry resulting in gold being dissolved from the ore Activated carbon is then fed into the process from the opposite direction against the slurry stream and as it moves through the CIL tanks dissolved gold adsorbs onto the activated carbon
At this part the applicability of CIL process in gold recovery with thiourea was investigated for the first time As a result of the experiments although higher gold leaching extents were obtained in CIL process the increase in extent was about maximum 8% and the highest gold leaching extent was obtained as 75% at the end of the 5th hour
CIL stands for carbon-in-leach This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process
Since its establishment 20 years Xinhai has been committed to the Research and development of cyanide gold process technology and equipment after the constant study of Xinhai research technicians Xinhai has formed a set of efficient environmental energy-saving and economic Xinhai gold CIL process

Process introduction Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore By cyaniding and carbon leaching crushed gold ore slurry simultaneously CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%
Carbon In Leach (CIL) Production Monitoring System It is a concern to know that the cost of retrieving the gold ore from deep below the surface of the ground bring the ore body and waste material to the surface crush and mill the ore to a fine slurry in order to process and recover the gold These initial costs (at a guess)
