Carbon in pulp Wikipedia

Carbon in pulp 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. Activated carbon acts like a sponge

01/01/2016· By replacing the Merrill–Crowe zinc cementation step, carbon-in-pulp (CIP) and carbon-in-leach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores (e.g., high-clay ores), at lower capital and operating costs and higher metal recoveries. In a fortuitous bit of timing, this technology became available as the world gold industry entered a period of

11/04/2018· CIP ( Carbon In Pulp) process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high-grade silver as well. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for Carbon In Pulp process in China: PH=10-12, sodium cyanide concentration is not less than 0.015%, the particle size of

of concentration 10–25 grams of carbon per litre of pulp (0.5 to 1.2% by volume carbon). The carbon is retained in each reactor by means of screens having an aperture of 0.6–0.8 mm which allows pulp to flow through and out of the reactor whilst retaining the carbon in the reactor. The gold aurocyanide complex in the aqueous phase is

Carbon in Pulp Plant

Sslurry at a rate of approximately 3.785 cu. m. per minute (1,000 GPM) is placed in contact with activated carbon. A simplified flow-sheet of the CIP Plant is shown in Figure 2. For years it has been known of the affinity of activated carbon to adsorb preferentially the gold and silver in cyanide complex form. This operation takes place in five circular tanks that provide a total pulp

Dynamic simulation of the carbon-in-pulp and carbon-in

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

29/01/2019· Carbon in pulp process. Gold Carbon-in-pulp (CIP) production is the sequential leach, then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. CIP process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the

DYNAMIC SIMULATION OF THE CARBON-IN- PULP AND CARBON

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. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank. This paper presents a dynamic model that describes, with minor

Gold CIP/CIL Processing Plant_Dongding Machine

CIL (Carbon In Leach) leaching process, that is, carbon leaching gold extraction, is a process of adding activated carbon to the pulp and leaching and adsorbing gold at the same time, which simplifies the CIP (Carbon In Pulp) process. The two steps of leaching pulp and activated carbon adsorption are one step, which reduces management costs while

El proceso CIP (carbon in pulp), que fuera desarrollado en Sud África en la década del 70, es considerado el avance tecnológico mas significativo de los últimos tiempos en cuanto a métodos aplicados a la recuperación de oro (Afenya, 1991; Hausen y Bucknam, 1985). No obstante esto en nuestro país aun no se ha implantado un sistema de recuperación de oro utilizando este proceso. En
