Carbon Adsorption Columns - Hydrometallurgy: Leaching

We ran a milling in cyanide CIL plant for reprocessing a gold tailings dump for one and half years. 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.

Ways to Recover Gold from Cyanide Heap Leach Solutions

Oct 14, 2018  Carbon in Column (CIC) The essence of the carbon-in-column process alternative is the adsorption of gold from alkaline cyanide solution by activated carbon. For typical carbon-in-column operation, the cyanide leach solution is pumped upward through columns at a flowrate of 15 to 25 gpm/ft², fluidizing the packed bed of activated carbon (16×30 ...

Why Put a 'V' in your CIC? - Morrison-Maierle

May 14, 2020  The pregnant solution flows through the carbon columns, which are generally situated in a step-down arrangement so that the overflow from the highest elevation column will flow to the next column. The gold absorbs onto the surface of the carbon. The loaded carbon is periodically removed from the columns and sent for stripping.

Process Design Manual For Carbon Adsorption

The filtration function of a carbon column is naturally affected by influent solids. Since solids frequently slough off of a carbon during operation, the influent and effluent from any carbon process should be characterized specifically for suspended solids and turbidity.

Does Carbon Load Affect the Retention Times from Your Columns?

Jul 30, 2018  The columns tested had percent carbon loads between 5% and 18%. What does affect the overall retentivity of a column is the phase ratio — which includes the pore volume and overall surface area. If columns with the same carbon load but different phase ratios are compared, the columns with higher phase ratios have longer retention times.

Activated Carbon for Gold Recovery Puragen Activated Carbons

Carbon in Leach: Carbon in leach, or CIL, occurs when the activated carbon is added to the slurry before any leaching occurs. The gold is both leached and adsorbed simultaneously. Carbon in Column: Carbon in column, or CIC, is a completely different process. After leaching, the gold-cyanide solution is poured into massive columns packed with ...

Carbon is found in the sun and other stars, formed from the debris of a previous supernova. It is built up by nuclear fusion in bigger stars. It is present in the atmospheres of many planets, usually as carbon dioxide. On Earth, the concentration of carbon dioxide in the atmosphere is currently 390 ppm and rising.

Au Recovery Using an Activated Carbon Column SpringerLink

Oct 26, 2012  The feasibility of a process involving the use of activated carbon in a multistage column (NIMCIX contactor) for the recovery of gold from unclarified pregnant solutions was investigated on pilot-plant scale. It was found that satisfactory extractions, corresponding to a recovery of 99.6 percent, can be achieved with an average gold concentration of 0.0077 p.p.m. in the barren solutions from a ...
