Metal recovery will involve carbon in column (CIC) and tank cyanidation and carbon in pulp (CIP) recovery. The loaded carbon will be transported to Newmonts carbon stripping and refining facility at Carlin for final processing, resulting in the production of g dor bars.
CIC (Carbon in Column) for Heap leaching dilute cyanide solution percolate over a heap of crushed ores and is then pumped through activated carbon columns All require a maximum g loading with rapid adsorption kinetics. It is important to choose the most suitable activated carbon for the process of the g recovery because each loss of
It is much easier to quot;concentrate upquot; g from the solution phase than from the solid phase. Activated carbon is an adsorbent that increases the concentration of g in the solution phase. For example, an ore containing 3 g/t is leached, mixed with carbon, which loads to 3
Carbon columns consist of large columns (5 to 8 ft diameter) and 15 to 20 feet in height, charged with activated carbon. The minimum load of carbon rule of thumb is one pound of activated carbon per 0.1 ounce of g present in the solution.
Carbon in pulp (CIP) is an extraction technique for recovery of g which has been liberated into a cyanide solution as part of the g cyanidation process. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process.
pulp (CIP) or carbon in column (CIC) circuits. The g leaching process starts with comminution. The run of mine ore is crushed and ground to a fine particle size. Water is added to the process to create a mud like slurry. The slurry is then pumped into a thickener, where the g bearing particles sink to the bottom, where they are fed for further downstream processing. Typically, the next step in the recovery
Carbon in Column (CIC) Process Plant Mining Industrial. HEA was asked to design a CIC process plant to be constructed at a new mine in Northern Nevada. During this effort, HEA developed a complete 3D Model to be used for visualization and interference checks. Ultimately the model was used to generate 2D construction drawings.

Activated carbon effectively removes the g from the cyanide, as the g is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carbon in pulp), CIL (carbon in leach) and CIC (carbon in columns).
Activated carbon plays an important role in mining applications. Particularly in g recovery, activated carbon is the key element in CIC, CIL and CIP processes. As a major manufacturer of activated carbon specialized for the g mining industry and precious metals recovery, we service some of the worlds largest mining companies.
ACTIVATED CARBON COLUMNS. Above the top of the first column there is a mixing system that is used to mix properly two flows. Its volume is 800 ml and the flow that receive is about 20 l/h so its residence time is 2.4 minutes, time enough to mix the two flows of 19.5 and 0.5 l/h.
The g free leach solution is then recycled, while the carbon is processed to remove the concentrated g. Carbon Fines Removal Filter Press. In each of the CIC, CIP, and CIL processes, the g that has been adsorbed and concentrated on the activated carbon is then recovered from the carbon by elution.
Carbon In Column (CIC) With CIC operation, the g cyanide solution flows through a series of fluidized bed columns in an up flow configuration. It is most commonly used to recover g and silver from heap leach solutions, which are often high in solids content.
Activated carbon effectively removes the g from the cyanide, as the g is adsorbed into the pores in the carbon. This has spawned technologies such as CIP (carbon in pulp), CIL (carbon in leach) and CIC (carbon in columns). More recently, SGS has lead the g processing industry with the development of resin based technologies.
Jinshan G Mines Inc., now China G International Resources Corp. completed a 20,000 t/d g recovery facility, heap leaching, carbon in column (CIC) g absorption, carbon stripping, carbon regeneration and acid washing, bullion refining, and reagent systems.
CIC = Carbon in column, CIL = Carbon in leach, CIP = Carbon in pulp, CL = Cyanide leaching, EW = Electrowinning, FL = Flotation, GC = Gravity concentration, PO = Pressure oxidation, RIL = Resin in leach, S = Smelting, TH = Thickening, ZE = Zadra elution, ZP = Zinc precipitation.
In the g industry, the use of coconut shell activated carbon to separate g from cyanide leaching solutions has become an industry standard for efficient g recovery in Carbon in Leach (CIL), Carbon in Pulp (CIP) and Carbon in Column (CIC) operations.
Carbon in columns During this process, the cyanide leaching solution passes through columns filled with ore. The process is highly effective for removing g from low grade ore. Resin Recovery Technologies Resin RIL (Resin in leach)/RIP (Resin in pulp) In recent s, resin is replacing carbon as the g recovery substrate of choice.
1. Carbon In Column (CIC) With carbon in column operation, solution flows through a series of fluidized bed columns in an upflow direction. Columns are most frequently open topped, but closed top pressurized columns are occasionally used. Carbon columns are most commonly used to recover g and silver from heap leach solutions.
Carbon in column or Circuits (CIC) Carbon in column or Circuits are typically used to recover precious metals from solutions as opposed to slurries.The design of CIP/CIL/CIC is closely related the design of agitated leach circuits. The primary consideration is that the use of GAC to remove g
The plant is designed to process 5 t of carbon per day using an absorption, desorption and refining process to extract g from the pregnant solution to produce the g dor. The g ore processing facilities will include the following unit operations Cru ..
Dec 17, 1991The heated solution desorbs or quot;stripsquot; the g from the carbon in the strip column and passes it on to an electrowinning cell. In the electrowinning cell, a DC current is connected through a cathode wrapped with steel wool and an anode of mild or stainless steel.
g, which were associated with sulphide minerals, were recovered. By regrinding, roasting, and cyanidation of the flotation concentrate, the g dissolution recovery was in the range of 87.8 to 98.4%. The carbon in column method was used to recover 98% of the g from the solution. Keywords g ore, pyrite, flotation, roasting, cyanidation
The g cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon in leach. This is a g extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in
We were achieving 60 70% dissolution in the mill then followed by adsorption in 6 CIL tanks.We are now looking at modifying the process and introducing carbon in column adsorption on the primary classification over flow which is 20 30% solids and grind 80% passing 75 microns.
In spite of the importance of the process, no consensus has been reached regarding the mechanism by which species are adsorbed on activated carbon. The carbon sizes from as coarse as 6 mesh to as fine as 28 mesh have proved to be effective in practice depending on Carbon in Leach (CIL), Carbon in Pulp (CIP) and Carbon in Column (CIC).
Carbon in Column (CIC) Process Plant Mining Industrial HEA was asked to design a CIC process plant to be constructed at a new mine in Northern Nevada. During this effort, HEA developed a complete 3D Model to be used for visualization and interference checks.
Calgon Carbons high quality GACs are proven to maximize recovery efficiencies by reducing g loss and minimizing carbon consumption when used for Carbon in Leach (CIL), Carbon in Pulp (CIP) and Carbon in Column (CIC) g extraction techniques.
During adsorption the entire g cyanide complex becomes attached to the carbon. The g attached to the carbon is then desorbed by a cyanide solution from which it can be recovered by electrolysis. The desorbed or stripped carbon can be regenerated by heating it
