The gold is stripped from the resin using a hot caustic solution and then recovered by conventional electrowinning. No thermal resin regeneration is required. The G-Rex system can be used for selective separation of gold over copper; silver over copper; gold and silver over copper or other dissolved metals as required.

meaning of electrowinning in gold processing

The electrowinning process is a key method for precious metal recovery and can mean big business especially when processing gold plated components. The gold is actually recovered from aurodicyanide solutions produced by the elution of loaded carbon and this is responsible for driving the resulting electrochemical reactions.

What is Electrowinning? - wiseGEEK

Electrowinning is a process used to remove metal ions from liquid solutions such as rinse water, plating baths, and used process solutions. Most often used to recover precious metals, it relies on an electronic current to plate the metal ions onto a cathode.

Gold Processing Plant---Advantage. High-efficiency: when the grade of loaded carbon reaches 3000g/t, the desorption rate can reach more than 96%, the barren carbon tenor with this equipment comparing with that of normal desorption electrowinning equipment will reduce to its one/ fourth.

Ore processing - Waihi Gold

The pregnant eluate (1) is passed through a series of electrowinning cells (2), containing cathodes in the form of stainless steel plates. The gold and silver migrates and attaches itself to the stainless steel cathodes. The cathodes are then rinsed, yielding a muddy sludge, and the cathodes are reused.

Electrowinning and Smelting - Resource Book

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).

Electrowinning gold processing | Rigaku Global Website

After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), or Carbon Column (CC). Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.

Gold processing | Britannica

With E.B. Miller's process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill's electrorefining process (introduced in Hamburg, Ger., in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refining.
