Gold CIL & CIP Gold Leaching Process Explained CCD
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. 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
Gold CIP Processing,Gold CIP Plant,Gold CIP Production
Gold CIP Production Line. Process Introduction . CIP (Carbon in pulp) process is a high efficient method to leaching and recovering gold from gold ore, The most different from CIL process is in CIP process, gold leaching and adsorption are separated, first leaching, and then adsorption. Now it is being replacing by CIL process progressively. But it still have a lot of application. Application
Improving the recovery of gold and copper in a CIP
One detrimental effect of the changes made to improve the gold recovery was a high residual cyanide content in the CIP tails. This was overcome by the use of the Inco process at a cost of 20 cents per tonne ore treated (current cost is 35 cents/tonne) (Zimbabwe currency).
MODELING OF THE CARBON IN PULP (CIP) PROCESS IN GOLD
Modeling of the carbon in pulp (CIP) process in gold cyanide leaching plants 847 same Q, C. Thus, optimization of the CIP plants would be possible after finding the model parameters by using the real plant data. Results and discussion The model parameters and the regression coefficient (R2) values for each models were
Cyanide control in the metallurgical process of gold
the plant cyanide addition rate. Cyanide control in the metallurgical process of gold extraction in AngloGold (S.A.) by B.J. Vorster* and S.R. Flatman† Synopsis AngloGold South Africa region currently consists of twelve gold plants. These plants use a combined total of $20 million of cyanide per annum. Of this, the major portion (60%) is consumed at two Ergo dump retreatment plants
How to Differentiate Gold CIP & CIL Production Line?
04/01/2017· 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

The process design of gold leaching and carbon-in-pulp
African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all non-refractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the
MODELING OF THE CARBON-IN-PULP (CIP) PROCESS IN GOLD
The Turkish gold cyanide leaching CIP plants, Bergama Ovacik, Gumushane Mastra and Eskisehir Kaymaz were modeled by using gold concentrations, solution, and solids samples from adsorption tanks without a need of laboratory work. Five carbon adsorption models were used namely k-n, Nicol-Fleming, Dixon, Film Diffusion with Langmuir isotherm and Film Diffusion with Freundlich isotherm (Johns
Factors influencing the rate of gold cyanide leaching and
The profiles of gold in solution for “CIL 1” and “CIP” show that the CIL plant performed poorly compared to the CIP plant, under the same operating regime, with predicted gold barren solution losses of 0.09 mg/L for CIL versus 0.01 mg/L for the CIP plant configuration. This difference was equivalent to almost 200 kg of gold losses per annum, which is worth $7 million pa at current gold
Cyanide Consumers in Gold Leaching Process
In many gold deposits, if gold is associated to arsenopyrite, there is a serious problem when gold is finely disseminated in the crystalline structure and the liberation of gold particles could be difficult. The presence of stibnite, realgar and orpiment is a problem due to react with cyanide at pH values higher than 10. These minerals are oxygen and cyanide consumers and the products formed

Recovering Cyanide From Gold Plant Tailings
The ability to recover cyanide from gold plant tailings has been known almost as long as the cyanidation process has been practiced, but there has been little incentive to process tailings in this way in the past. With . the development of technologies that make it possible to recover and recycle free or complexed cyanide directly from gold plant slurry tailings, which indicates, on stone at

Carbon in pulp Wikipedia
Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.
