GOLD ELUTION AND ELECTROWINNING At Nesch Mintech we have ten (10) gold elution machines. Three of them are high pressure machines and the rest are low pressure machines. High pressure machines operate for 24 hours while the low pressure machines operate for 48 hours.
The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate).
By pressurising the electrowinning cell, the gold-cyanide complex in electrowinning is destabilised and increases the electrowinning efficiency, lowering solution tenors returning back to the elution column and providing the optimal kinetics for rapid
Electrowinning is used in modern gold mining operations to recover gold from solution using electric current. This is necessitated by the need to recover all valuable gold during downstream operation with the advantage of increased fineness and reduction in the refinery cost of the final bullion as it will have lesser base metals.
Mar 31, 2016· One bed volume (thirty minutes) into the elution stage the eluate pump is started and pregnant solution from the eluate tank, is pumped up into the electrowinning cell on the first floor of the goldroom. It then flows back into the eluate tank. As the solution flows through the electrowinning cell, gold is plated on to the steel wool cathodes.
By pressurising the electrowinning cell, the gold-cyanide complex in electrowinning is destabilised and increases the electrowinning efficiency, lowering solution tenors returning back to the elution column and providing the optimal kinetics for rapid eluting of the precious metals off the loaded carbon.
During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and recycled to the carbon bed for reuse (see Figure 1).
