“…It has obvious technical advantages in the purification and separation of multi-metals [17]. It is widely used in acidic solutions, including sulfuric acid [18], hydrochloric acid [19], nitric acid, and cyanide [17,20] to extract low concentrations of copper [17], cobalt, nickel [21], zinc [19], gold [16], silver [20], and so on [16]. Because of the relatively high-speed motion of the electrolyte and electrode, cyclone electrodeposition avoids the concentration polarization caused by the slow flow of electrolytes in traditional electrodeposition process [17], reduces the thickness of the diffusion layer [5,22,23], and enhances the mass transfer while minimizing ion exchange.…”

“…This technology can not only realize the high purity extraction of low concentration metal ions but also realize the collection and recovery of electrolytic mist, which has good economic and environmental benefits. The process of metal recovery by cyclone electrodeposition is widely used in the direct electrodeposition of metals in low-concentration solutions [16]. Many scientists have studied the effects of different experimental conditions on the efficiency of metal recovery in the cyclone electrodeposition process.…”

A strategy to determine the effect of Cd2+ on the electrodeposition of copper from a copper electrolyte by cyclone electrowinning is presented. The concentration of Cu2+ in the copper electrolyte with different Cd2+ concentrations was determined by atomic absorption spectrometry (AAS). It indicated that the current efficiency, the rate of electrodeposition, and the rate copper electrodeposition decreased with the addition of Cd2+ in the three stages of electrodeposition. The current efficiency declined from 99.6 to 79.2% and the copper electrodeposition rate declined from 52 to 40% in the first electrodeposition. The current efficiency had no significant change, and the copper electrodeposition rate declined from 88 to 77% in the second electrodeposition. The current efficiency declined from 72.6 to 40.3%, and the copper electrodeposition rate was all at 99% in the third electrodeposition. The influences of the Cd2+ concentration on the purity and morphology of cathode copper were investigated. The effect of Cd2+ concentration on the purity and morphology of cathode copper was also studied. In the three-stage electrodeposition, the addition of the Cd2+ concentration mainly affected the microstructure of the cathode copper, but it had little effect on the purity of the cathode copper. The higher the amount of Cd2+, the rougher the morphology of the cathode copper and the larger the gap between the grains; the higher the amount of Cd2+, the lower the electrodeposition rate and current efficiency, though the reduction was small.
