electrowinning. A study of the nucleation and growth was conducted in a synthetic electrolyte (40 g/L Cu, 160 g/L H. 2. SO. 4, 20 mg/L Cl-) with the addition of HydroStar or Cyquest N-900 using potential step measurements. The current responses generated were compared to theoretical models of nucleation and growth mechanisms. The nucleation

An electrowinning cell of novel design has been described by Treasure (2000).Named as EMEW R cell, it consists of a cylindrical in place of planar electrodes. The outer tube is the cathode and the inner one is anode. The diameters of the electrode tubes are sized according to the particular application to minimize cell voltage for a given solution chemistry.

Thus, there is an escalating need to recover metals from e-waste for sustainable management of metal resources. Hydrometallurgical processing of e-waste, involving copper (Cu) leaching and its subsequent recovery from pregnant leach solution (PLS) via electrowinning, has emerged as an efficient strategy to close the recycling loop.

Due to the low cell voltage during electrowinning in the authentic industrial wastewater the energy consumption of copper recovery (ca. 2.5 kWh/kg Cu) was similar to the values reported in industrial electrowinning (1.8–2.5 kWh/kg Cu), which are conducted in highly concentrated copper solutions (ca. 50 g/L) without a high concentration of iron.

The mechanism of the Cu-NH 3 based ECC electrolysis, including the electrochemical CO 2 desorption and electrochemical NH 3 regeneration, is shown in Fig. 2.The redox-active couple of Cu 2+ /Cu (s) is used as the electrochemical medium, in which NH 3 can bind more strongly with Cu 2+ to form Cu(N H 3) n 2+ than with the CO 2 to form carbamate. The …

In view of the challenges of high energy consumption or inefficiency (low current density) for current electrochemical CO 2 capture, the present work proposes an energy-efficient electrochemical approach - electrowinning-coupled CO 2 capture (ECC) - that integrates commercial Cu electrowinning technique with amine-based CO 2 capture.

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. Decreasing Cu codeposited will reduce reftnery costs. Direct current was applied to the cell in pulsed and square wave
