The capacity of coconut shell activated carbon to absorb gold can vary based on several factors, including the specific properties of the carbon, the concentration of gold in the solution, and the conditions of the adsorption process. However, in the context of gold recovery in mining operations, a typical adsorption capacity for coconut shell activated carbon can range from 3,000 to 10,000 milligrams of gold per kilogram of carbon.
This means that 1 kilogram of coconut shell activated carbon can absorb between 3 to 10 grams of gold under optimal conditions. The exact amount will depend on factors such as:
Coconut shell activated carbon Quality: Higher-quality activated carbon with more surface area and better pore structure will generally have a higher adsorption capacity.
Gold Concentration: Higher gold concentrations in the solution can lead to higher adsorption rates.
Contact Time: Longer contact times can increase the amount of gold adsorbed by the carbon.
Presence of Other Metals: Other metals in the solution can compete with gold for adsorption sites on the carbon.
In industrial practice, the actual adsorption capacity can be determined through laboratory testing and pilot plant studies specific to the conditions and materials being used.
