process, (iii) electrowinning and (iv) ion-exchange / solvent extraction. Traditionally, Merrill-Crowe process was used to remove gold from a cyanide solution by using zinc dust to precipitate gold from its solution. Carbon adsorption is increasing using in newer plants for gold .
Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4 The overall reaction is the combination of two electrochemical half reactions.
Pre-concentration significantly reduces energy requirements and lowers the carbon footprint of plant operations. Gekko's modular systems are used worldwide for free gold, complex gold, exploration, alluvial or hard rock, and diamond applications. Where appropriate, Gekko source and include processing equipment from other suppliers if required.
Electrowinning is the oldest industrial electrolytic process. The English chemist Humphry Davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide.. Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in .

Strategies For Optimisation of Gold Processing Plants. by Chris Campbell-Hicks . ABSTRACT. Optimisation of many gold oxide processing facilities, in most cases, either does not really take place or if it does take place it happens too late or takes too long.
SELECTIVE ELECTROWINNING OF SILVER AND GOLD FROM CYANIDE PROCESS SOLUTIONS By F. H. Nehl,1 J. E. Murphy,2 G. B. Atkinson,3 and L. A. Walters2 ABSTRACT The U.S. Bureau of Mines investigated the selective electrowinning of Ag and Au from cyanide solu tions contaminated with Cu with the goal of decreasing the amount of Cu codeposited.

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore.
Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.
