abstract = "In metallurgical operations, cyanidations is the predominant process by which gold and silver are recovered from their ores and it is recognized that the Carbon in Pulp, Merrill-Crowe process or the Ion Exchange resins are used for the concentrations and purification of gold and silver from cyanide solutions. Among several options are available for recovery precious metals from cyanide solutions, Electrocoagulation (EC) is a very promising electrochemical treatment technique that does not require high concentrations of gold and silver in solutions. First, this study will provide an introduction to the fundamental concepts of the EC method for recovery precious metals from cyanide solutions. In this research, X-ray Diffraction, SEM and Transmission Mossbauer Spectroscopy were used to characterize the solid products formed at iron electrodes during the EC process. The results suggest that magnetite particles and amorphous iron oxyhydroxides present in the EC products remove gold and silver in 5 minutes.",
