Gold cyanidation Wikipedia

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents

(PDF) REVIEWING THE OPERATION OF GOLD ELECTROWINNING CELLS

The electroreduction of gold thiosulfate to gold is kinetically faster than the reduction of gold cyanide to gold; gold thiosulfate is reduced at -0.15 V vs SCE and is independent of pH for values of above 4. However the standard EW is especially problematic in the presence of a great excess of unwanted cupric and cuprous ions.

Purification of Gold by Electrolysis

The Moebius Process of Purification of Gold by Electrolysis is now in successful operation and is said to be specially suitable for refining copper bullion containing large proportions of silver and gold with small quantities of lead, platinum, and other metals, but is chiefly used in parting dore silver containing not more than 20 per 1,000 of base metals. The apparatus required consists of a

Electrowinning and Smelting Resource Book

Gold Cyanide Ion + Electron Solid Gold + Cyanide Ion The rectifier acts, as a battery supplying the electrons (electricity) required for the reaction to proceed. An electron is the basic unit of electricity, The gold cyanide complex is 'split' into a solid gold particle attached to the cathode and cyanide ions that remain in solution.

Electrowinning an overview ScienceDirect Topics

Recognized methods of elution of strong-base resins use zinc cyanide, ammonium thiocyanate, or acidic thiourea. Although each method has advantages and disadvantages (Fleming and Cromberge, 1984), no single method seems to be appropriate for all cases.For example, Fleming (1989) used the zinc-cyanide method for a conventional strong-base resin (A161RIP) used at the Golden Jubilee RIP plant
