Carbon-in-Pulp ScienceDirect
The pump cell combines pumping, screening, and agitation in a single-drive unit with a high rate agitation. The design permits high carbon densities, resulting in short residence times for the pulp. As a result, pump-cell dimensions are much smaller than typical carbon-adsorption stages in CIP or CIL operations.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 a result of the gold adsorption mechanism, which is a chemical ACTIVATED CARBON IN GOLD RECOVERY Kemix

For the extraction processes to function efficiently a specific carbon granule size must be maintained.

Therefore, before carbon modelling testwork is undertaken, SGS must establish the rheological properties of the pulp sample to determine the optimum leach and adsorption pulpPublisher Summary. This chapter focuses on the advances made in the design and operation of carbon-in-pulp (CIP) and carbon-in-leach (CIL) plants.

Technical Paper Gold-Selective Ion Exchange Resins vs.
Activated carbon is widely used for gold recovery from cyanide leach liquors via carbon-in-leach (CIL) or carbon-in-pulp (CIP) technology. From all the base metals cyanide complexes typically present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded onto activated carbon(6).After the development of cyanide processing of gold ores over a century ago, no significant advances in technology took place until the introduction of large-scale carbon-in-pulp (CIP) and carbon-in-leach (CIL) plants in the 1970s. CIP is today the preferred route in the western world for the recovery of gold from cyanided pulp.Resin-in-pulp and resin-in-solution ScienceDirect

Modeling and optimization of Carbon in leach (CIL) circuit
The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon. Although the earliest process was in South Africa in 1890, CIP/CIL was first introduced in gold processing in 1949 at San Andreas (Honduras) (Marsden and House, 2006). As the ore grades have deteriorated from around 12 grams per tonne in 1950 to
