The gold extraction process involves finely grinding the ore using a carbon-in-pulp method, where gold is solubilized in tanks through cyanide leaching. Granular activated carbon is added to adsorb gold from the solution. Now loaded with gold, the carbon is separated from the slurry through coarse screening.
The gold reserves of the country are estimated at 8.5 million ounces, and there is a high demand for activated carbon because gold recovery techniques are migrating from traditional amalgamation to a more technical process, like cyanidation leaching and AC adsorption process .

carbon-in-pulp "renaissance" with the August, 1973, commissioning of the CIP circuit at Homestake Mining Co.'s plant in Lead, South Dakota (then a 2,200 st/d mill). But the fact is, that the process was used commercially at least 22 years earlier, demonstrating once again that much that is new
Carbon in Pulp Xi an Desen Mining Machinery Equipment Co. Ltd. Carbon in Pulp (CIP) is an extraction technology used to recover gold which has been released into the cyanide solution as part of the gold cyanidation process. It is used in most industrial applications. CIP leaching and adsorption occur simultaneously. CIP is a slow process.
Carbon pulp extraction process (CIP method and CIL method) is to put activated carbon into the cyanidation pulp, and the dissolved gold is adsorbed on the activated carbon, then the gold is extracted from the activated carbon.This process mainly includes the following steps: the preparation of leaching materials, agitation leaching and countercurrent …
Introduction of Rock Gold CIP Process Plant. The gold carbon in pulp (CIP) Processing refers to the process of grinding all the gold ore into a slurry (-200 mesh content accounts for more than 90-95%). ... or multi-layer thickeners.
