Elution and electrowinning of gold from gold-selective ...
01-04-1995 Electrowinning is compatible with the elution technique and provides a simple and effective method of recovering the gold from the eluate. The composition of the eluate does not affect the electrowinning efficiency much and it is therefore possible to operate both the elution and the electrowinning at their optimum efficiency.

High Efficiency Elution and Electrowinning Plant GOLD ...
1.3 Elution - Electrowinning Circuit Elution and electrowining circuits form a packaged integrated pressure strip (IPS) system which works under high temperature and pressure so the elution circuit cancels the heat exchanger which is used in Zadra system. The pregnant solution ahs high temperature which is favorable to the electrowinning cell.

OPTIMIZING THE OPERATING CONDITIONS OF GOLD ELUTION
The continuous decrease of gold content in the stream and the variability of flow rate and temperature affect the elution and electrowinning processes. Low-grade eluate tends to be problematic for electrowinning as the impurities tend to “compete “with the gold for deposition current.

Optimizing the operating conditions of gold elution
The final gold product of Tau Lekoa mine has a low fineness. This is caused by high concentration of bases metals in the reefs. Some of these base metals together with gold are leached with cyanide and are loaded into carbon. If not adequately controlled, they may elute with gold and contaminate the final product in the electrowinning process.
MoreKemix - Electrowinning
Electrowinning Cell Process Eluates containing soluble gold and silver from either a ZADRA or an AARL type elution are suitable for recovery in the Kemix Electrowinning cell. Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution.

Electrowinning of gold copper ores - Hydrometallurgy ...
A typical elution would produce about 4kgs of gold and 5kgs of copper. The copper makes it difficult to strip the gold off the steel mesh cathodes. Which would be the best stage to eliminate copper, during cyanidation, adsorption or electrowinning. And how do i go about this. Please help. Thank you for in

Elution behaviour of metals from carbon - SAIMM
that generally mercury follows gold through the cyanide circuit (Zárate, 1985) and loads onto the activated carbon, but only partially elutes with the gold. This partial elution compounds the treatment difficulties, since a portion of the mercury reports to the electrowinning cells, and the remainder reports to the carbon regeneration kilns.
