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 leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously.
Modular heap leach recovery plants and water treatment systems with capacities up to 3500 GPM offer very economical alternatives to conventional field constructed plants. Currently, most of the custom fabricated equipment shown on this website is only offered on an EPCM or consulting/royalty type basis and not by lump sum pricing.
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 adsorption reactor. This loaded carbon may then be subjected to an acid wash by treating the carbon with a hot or cold ...
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 . It has become the first choice of modern gold mining and beneficiation plant design.

May 11, 2020· Carbon-In-Leach. Carbon-in-leach combines leaching with the carbon-in-pulp process, creating a single unit process operation. Usually this method is chosen when native carbon (a high organics load) is present in the gold ore, adsorbing the leached gold and preventing its recovery.
plant is specifically designed for easy installation at a remote site, and allows scope for future expansion, by using a pre-fabricated modular approach. The circuit includes screening, thickening, pre-leach, carbon in leach (CIL), carbon recovery and cyanide detox, including all ancillaries and utilities, with a provision for the future ...

MODULAR RECOVERY PLANTS. Since 1972, KCA has fabricated portable or modular carbon adsorption, carbon desorption, carbon stripping and Merrill-Crowe plants. KCA's plants have earned an outstanding reputation for quality, simplicity, ease of start up and fail-safe operation. Modular plants can be constructed for gold operations treating up to ...
effects. Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface. A variable order empirical
required for gold leaching by cyanidation. Another example of chemical interference is the presence of graphitic carbon in a gold ore. This species, which occurs naturally in many orebodies, particularly in the SW United States and West Africa, is able to re-adsorb gold cyanide from the leach solution, lowering overall gold recovery.
Particularly in gold recovery, activated carbon is the key element in CIC, CIL and CIP processes. As a major manufacturer of activated carbon specialized for the gold mining industry and precious metals recovery, we service some of the world's largest mining companies.

This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as
CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size (typically 90% passing 200mesh ) to ensure that all non-refractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multi-stage crushing, then ball milling circuits, typical of ball mill and hyrocyclones.
