The Metso Outotec Elution and Goldroom plant can be delivered standalone or as part of a holistic gold process solution to enable onsite production of gold dor . The elution plant is built from pre-engineered modules to reduce engineering, delivery, construction, and commissioning time and cost. The plant also features a heat recovery circuit ...

The process allows the eluant to pass through fresh carbon twice, thereby reducing the volume of the gold-loaded eluant. This, in turn, reduces the size of the electrowinning or zinc precipitation circuits. The process also improves elution efficiency when barren electrowinning solution is recycled in the elution process.

Elution & Electrolysis System. Prominer‘s Elution & Electrolysis system is an integrated processing system striping gold from gold-loaded carbon under high-temperature high-pressure cyanide-free conditions. Developed from Zadra and AARL by raising elution temperature and replacing the atmospheric-pressure electrolysis cell with a pressure ...

The filtrate is then sent to the elution vessel, V-401, where the elution process begins. The gold is eluted into a water solution from the carbon by the American-Anglo Research Laboratories (AARL) method, leaving the barren carbon behind. Figure 5 shows the carbon adsorption and AARL elution processes. The loaded eluant, Stream 37,

Dec 03, 2019 Process of electrowinning of gold, also called electric extraction, is a process of recovering gold by desorption electrolysis of gold loaded carbon under high temperature and high pressure conditions. It is an important part in the gold cyanidation process. Why is this process widely used in mineral processing plants?

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. The presence of ...

The gold-rich solution from the elution process, the electrolyte, is circulated through three parallel electrowinning cells over a period of 16–24 hours. Gold and other metals are precipitated on steel wool cathodes, which are submerged in the circulating electrolyte. At the anodes, oxygen is formed and degradation of cyanide occurs.
