Elution behaviour of metals from carbon

2009-10-15 · shown in Figure 3. From the gold recovery curves, it was evident that both the C1 and C2 carbon samples eluted in a very similar manner, despite the loading for the C2 carbon being significantly less than the C1 carbon. It was also clear that the acid washing stage had little impact on the elution of gold.

Factors affecting the elution of gold cyanide from ...

1994-1-1 · Likewise, Davidson [5] considered the temperature and reagent cyanide addition to be the most important factors affecting gold elution. In cases where the loaded carbon contained large amounts of calcium carbonate, the temperature and acid washing of the carbon were considered to be most important for efficient elution [6].
