Factors affecting the elution of gold cyanide from

01/01/1994 The gold elution profiles presented were obtained by performing identical elutions in the glass column and in a stainless steel column which was 300 times larger by volume. These columns had h/d ratios of 11.3 and 7.5 respectively. The same flow rate of eluant, expressed as number of bed volumes per hour, was used. Very similar elution profiles were measured for both cases, with only a slightly sharper profile for the glass column

Elution behaviour of metals from carbon

Gold elution rates increased with increasing NaCN in the soak solution, with profiles approaching a similar overall recovery of gold. This data is also consistent with the literature, which shows the rate of gold elution from carbon utilizing a Zadra system at 95°C increases with increasing cyanide concentration. (Adams and Nicol, 1986).

Elution behaviour of metals from carbon

to the flushing of the NaCN + NaOH solution from the column, the elution of gold was poor. However, as the soak solution was displaced with distilled water, there was a large peak in the concentration profile, followed by a tail which was typical of elution processes. The recovery profile showed that within 2 200 g of eluant (~15 BV), the recovery of gold was >90%, and the profile was similar

01/01/2016 This means that separate columns are required for elution and acid washing because the butyl rubber lining frequently used in AARL columns is not suitable at these temperatures. At Misima Mines in Papua New Guinea the AARL elution was run at two temperature levels to provide two eluates: one high-gold low-silver and the other low-gold high-silver ( Zandee, 1993 ).

Carbon in pulp Wikipedia

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Numerous articles have appeared on the mechanism of the adsorption of gold cyanide onto activated carbon. In contrast, little information is available on the mechanism of elution of the adsorbed gold. It is the objective of this article to formulate such a mechanism on the basis of batch and column elution tests without analyzing adsorbed species on the carbon directly.
