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

Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.

 — Gold room operations can be as simple as a single electrowinning cell and eluate tank, drying oven and smelting furnace. Or they can incorporate gravity-concentrate tabling, separate concentrate leaching, multiple electrowinning cells, cell-mud handling and filtration, and large-scale smelting operations. The complexity of the operation generally …

 — The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold …

High Efficiency Elution and Electrowinning Plant. Working Principle . 1.1 Elution. CN- or OH- dissolved in desorption solution is easier than Au(CN)2- to be absorbed by the activated carbon which causes Au(CN)2- absorbed on loaded carbon is replace by CN- or OH- and the reversible balance of of gold adsorption is broken. This processing is ...

For an agitated leach plant processing 2 g/mt gold ore, it requires a production rate of at least 5,000 mt/d of ore. Even in those cases, while the Carbon Converter has a payback of about one year, but it does not …

treated in a separate stream at Kopanang Gold Plant. The Kopanang Gold Plant is a modern plant that uses mill-leach-CIP- electrowinning processes. The gold from the electrowinning process is smelted centrally in another plant situated 5 km away from Kopanang. The quality of the final bullion is affected by the presence of base metals. …

The elution plant and goldroom completes the CIL/CIP/ CIC circuit, enabling stripping of gold from loaded carbon, electrowinning into gold sludge, and drying and smelting of sludge into doré bars. Carbon can then be reactivated for reuse in the circuit. Outotec's turnkey process plant solution includes:

 — Most process engineering companies readily design and build specification elution and electrowinning facilities for new gold-processing plants. In gold ore–processing applications, some research focus has been on the influence of impurities such as copper, 1., 2., 3. calcium, 4 and anode impurities 5., 6. on gold electrowinning efficiency ...
