However, the adsorption capacity of the adsorption equipment was decreased due to the decrease of the adsorption rate. At the same time, the flow rate of the solution through the carbon layer is fast, and the fluidized carbon bed can be formed, which accelerates the adsorption speed of the activated carbon to the gold-cyanide complex ion, which is beneficial to the improvement of the equipment efficiency.

Factors influencing the rate of gold cyanide leaching and ...

01-05-2011  But operating the plant at higher gold loadings slows the rate of adsorption of gold cyanide onto carbon and increases the gold losses in the barrens solution. This can be seen by comparing the profiles in Runs 2, 8 and 9, where the up-grading ratio was varied from 610 to 1000 to 1420, resulting in an increase in soluble gold losses from 0.001 to 0.003 to 0.007 mg/L.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

In the CIL circuit, adsorption of gold onto activated carbon is most effective at low temperatures, low cyanide concentrations, low pH and high gold concentration in solution (although some of these conditions aren’t practically achievable). By simply reversing these conditions, elution (desorption) of gold from the carbon occurs.

Adsorption / Active Carbon - Lenntech

Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is the solid. Activated carbonis produced specifically so as to achieve a very big internal surface (between 500 - 1500 m2/g). This big internal surface makes active carbon ideal for adsorption.

Adsorption - Wikipedia

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent.This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent). Adsorption is a surface phenomenon, while absorption involves the whole ...
