The CIL process The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as . ACTIVATED CARBON IN GOLD RECOVERY - Kemix
The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining. ... has been demonstrated by the recently introduced Kemix.
Apr 03, 2013· "Our contract includes the supply of nine MSP 500(P )pumping interstage screens and 18 launder gate valves for the carbon-in-leach(CIL) circuit, along with a 250 kg/h electric carbon regeneration kiln and two 8-cathode/9-anode electrowinning cells," says Kemix .
The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and Australia, from where they spread rapidly to all the gold producing regions of the world. ... This has been demonstrated by the recently introduced Kemix Pumpcell design of CIP contactors ...
•Carbon-In-Leach (CIL), Carbon-In-Pulp (CIP), Carousel CIP and Process Selection. 2. Activated Carbon What is Activated Carbon? Generic term for a family of highly porous carbonaceous materials, none of which can be characterised by a structural formula or by a chemical analysis.
Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields.
During this period, Kemix specialised in the design and supply of leach Agitators. A commitment to providing turnkey solutions to the industry saw Kemix expand its scope with the design and development of the Minerals Processing Separating (MPS) Interstage Screen.
A counter current method involves pulp flowing down a series of tanks with a reduced flow pumping carbon up the series of tanks to maximize gold on carbon loadings and minimize gold losses to tails. The interstage screens prevents carbon going down the circuit. MPS and MPS(P) Interstage Screens are semi-submerged top exit type screens.

ACTIVATED CARBON IN GOLD RECOVERY - Kemix. 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.
Kemix Carbon Adsorption. The methods are carbon-in-leach cil, carbon-in-pulp cip and pumpcell technology.Cil and cip are typically counter current operations while the pumpcell technology makes use of the carousel mode of operation.The cil mode of operation is when the leach and adsorption circuit are combined into a single process.A cil mode of operation has.
Extracting Gold By Carbon In Pulp Blogger. Carbon In Pulp is the absorption of compounds into carbon Dicyano Aurrat In the process of carbon in pulp adsorption occurs after the leaching of mineral ore slurry in a tank And during the washing the carbon in leach and adsorption occur simultaneously

HEAP LEACHING TECHNIQUE in MINING. Figure 3 Process categories based on leach recovery vs ore gold grade (McNab, B., 2006) 3. LEACHING IN THE NATURAL ENVIRONMENT Water is a universal low-polarity solvent in action in the nature Water soluble salts in ores tend to dissolve in percolating rainwater and are transported by
Our Carbon Retention Screens can be installed into Kemix and WesTech equipment, offering carbon-in-pulp (CIP) and carbon-in leach (CIL) designs. Global manufacturing base. Our global manufacturing footprint ensures we can get our carbon retention screens to you when you need them. Carbon Retention Screens are currently manufactured at three sites:
Kemix - Carbon Regeneration Kilns The carbon regeneration circuit is a process designed to restore the activated carbons ability to recover precious metals from Leached slurries.
These methods are Carbon-in-Leach (CIL) and Carbon-in-Pulp (CIP). CIL and CIP operations have a number of adsorption tanks placed in series. Pulp flows continuously from the first tank to the last, while carbon is pumped counter current from the last to the first tank. ... In Kemix's experience unsecured Interstage Screens will become ...
Carbon in pulp. Typically concentrations as high as 4000 to 8000 grams of gold per tonne of carbon (g/t Au) can be achieved on the final loaded carbon as it comes in contact with freshly leached ore and pregnant leach solution (PLS). This can be measured by comparing the amount of gold extracted from the carbon to the amount of carbon used. Get ...
The plant consists of six Kemix pump cells in a. ... The carbon in pulp (CIP) and carbon in leach (CIL) processes became firmly established in the gold mining industry in the 1980s, initially in ...
Carbon In Leach (CIL) Production Monitoring System It is a concern to know that the cost of retrieving the gold ore from deep below the surface of the ground, bring the ore body and waste material to the surface, crush and mill the ore to a fine slurry in order to process and .
However, during the innovative Kemix way to use the pump cell/carousel mode, the carbon stays in the same tank and only the leached solution moves from one tank to the other. When the carbon is loaded with gold, the tank is isolated, and the carbon is collected to move to the elution stage process.
The methods are Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Pumpcell technology. CIL and CIP are typically counter current operations while the Pumpcell technology makes use of the carousel mode of operation. The CIL mode of operation is when the leach and adsorption circuit are combined into a .
3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.
dressing process carbon in leach process for gold recovery p. carbon in leach process for gold recovery for iron in ethiopia. For Gold Processing,Gold Processing Plant,Gold Plant from Other Mining . the desorption rate can reach more than 96%, the barren carbon tenor with this . cyanide, the leaching rate of gold can get 91.45% which is perfectly good.
