Your % calcium on carbon values is fine. It is important to acid wash carbon to control calcium. You don't have to acid wash every cycle if your % calcium is below 1%. All you have to worry about is the % calcium on carbon. When calcium precipitates in the carbonate form onto the exterior surface of carbon it can also occlude fine ore particles.

Carbon strip circuits present a particularly challenging scale inhibition problem. Many of the factors that tend to promote scaling are present in these systems. For example, carbon strip circuits are run at high temperatures, high pH levels, and require long batch cycle times. Tortuous paths are encountered by the strip solution circulating ...

For efficient stripping of gold, from activated carbon, reversing the above is logical. Thus successful elution should be favoured by high temperature, high free cyanide, high pH, low ionic strength and the absence of calcium. This is an excellent starting point to commence elution optimisation.

WEBMetso Outotec's turnkey process plant solution includes: • Acid wash step to remove inorganics compounds from carbon • Elution step to strip gold from loaded carbon • …
Soak / wash the carbon for a couple of hours in 3%-5% HCL is often necessary to dissolve the junk, making for a cleaner strip of the gold-cyanide complex. A non pressurized elution strip can take up to 48 hours. Pressured systems can achieve it in less than 10 hours. Ideal flow rate is 2-3 bed volumes x hour.

Results showed that aqueous solutions of organic solvents could be effectively used to strip gold from activated carbon which compared favorably with Zadra and …
The most well known carbon-in-pulp plant remains the prototype Homestake plant in Lead, South Dakota. Operating since 1973, this facility treats 2130 tonnes of ore per day averaging 2.7 g gold per tonne. Homestake has also operated small silver carbon-in-pulp plants at Creede and Cripple Creek, Colorado since 1979.
30 (tons/h) Excellent gold capture and mass production capabilities. DETACH's gold washing equipment can collect gold powder with yields as high as 99%. It can process a large amount of input in a short period of time, resulting in excellent production. The DETACH Gold wash and separator equipment is simple to operate.
Stripping Gold & Silver from Carbon – Chemistry. Stripping of gold and silver from carbon is effected by means of two main processes (AARL and ZADRA). The main …
Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...
