Electrowinning of gold from a dilute solution using
ABSTRACT. The redox reaction mechanism of gold−cyanide [Au(CN) 2 −] during hydrocyclone electrowinning was investigated in this work by conducting Hull cell test, potentiodynamic polarization, and computational fluid dynamics (CFD) simulations.A leaching solution of waste printed circuit boards (WPCBs) was prepared as an Initially, the electrowinning tests were performed with solutions containing 100 ppm of gold, and then with solutions containing 10 ppm of gold. In both cases, the concentrations of the other components present in the solution were kept constant: copper 1000 ppm, thiosulfate (Na 2 S 2 O 3 ) 0.12 mol L −1 and ammonium 0.2 mol L −1 .Electrochemical study of gold recovery from ammoniacal

Energy Efficiency of Electrowinning SpringerLink
In electrowinning, most of the energy consumed is related to the electrical energy needed to drive the electrochemical reactions. For industrial copper and zinc electrowinning, the median specific electrical energy consumptions are 2.0 and 3.0 kWh kg −1, respectively [3, 4].This electrical energy consumption accounts for 80% of the total 2.2.5.3.2 Cobalt Electrowinning. The electrowinning of cobalt from aqueous chloride solutions is similar to the electrowinning of nickel from chloride solutions. The process produces cobalt with a purity greater than 99.95% Co. Current efficiency is ~ 90% with cell voltages of ~ 3.7 V. Current density is 200–250 A/m 2.Electroextraction an overview ScienceDirect Topics
