DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND …

Abstract - Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the …

Extraction of gold using cyanide

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Gold Extraction and Recovery Processes

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. Selected summary of patented gold recovery processes and …

THIOSULPHATE LEACHING

carbon-in- pulp (CIP) or carbon-in-leach (CIL) processes for the recovery of gold directly from leach pulps. Instead, SGS will evaluate the following gold recovery options for your project: • Resin-in-pulp technology involving direct recovery of gold thiosulphate from the leach pulp by adsorption on strong-base anion exchange resin.

Gold CIL & CIP Gold Leaching Process Explained CCD

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 …

gold adsorbed on the carbon is in equilibrium with the residual gold concentration in the solution, and therefore the low gold concentrations in the final stage can be adsorbed only if the pulp in this stage is contacted with unloaded carbon. The considerable difference in grain size between carbon and pulp particles permits an easy separation ...

Cyanide Gold Extraction Process - JXSC Machine

 · Cyanide Gold Extraction Methods. The existing cyanide gold plant in China’s gold mines basically adopts two types of gold extraction process, one is a so-called conventional cyanidation process for gold extraction by continuous countercurrent washing with a thickener, and the gold is replaced by zinc powder (CCD method and CCF).

(PDF) ACTIVATED CARBON FOR PRECIOUS METALS RECOVERY ...

Carbon tetrachloride is a good gauge of vapor phase adsorption capacity. The use of activated carbon in gold recovery combines physical adsorption, surface reactions and solution equilibrium. Therefore, these two standard measures of activated carbon quality are not necessarily good gauges for the use of carbon in gold recovery applications.

Leaching & Adsorption Resource Book

The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded with enough gold it is removed from the circuit and sent to elution where the adsorption process is reversed and the gold is stripped off the carbon back into solution, electrowon and smelted into bars.

During the past fifteen years significant progress has been made on carbon-in-pulp (CIP) technology for the extraction of gold. Most research on the mechanisms and kinetics of CIP subprocesses has focused on the adsorption step only; auxiliary unit operations such as elution have received less attention.

pulp is mechanically mixed and aerated with compressed air for one week, after which 60 kg granular activated carbon, made from coconut shells, is added to absorb the gold dissolved. The pulp is screened, allowing the finely ground ore particles to pass through, but the coarser carbon is captured, dried, and burned to ash. Borax

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.

The potential for resin-in-pulp (RIP) to replace CIP/CIL is discussed. The use of cyanide has generated environmental concerns because of its toxicity and therefore research on alternative gold recovery processes using non-toxic reagents is considered. The key candidates are: ammoniacal thiosulphate, thiourea and halide solutions.
