Summary: A clean approach was proposed to recycle copper from waste printed circuit boards using leaching, purification, and electrolysis. Ceric ammonium nitrate (CAN) was used as the leaching agent, and the leaching process followed the mixed control model with an apparent activation energy of 47.56 kJ/mol. The purified solution was used for electrolysis to produce high purity copper at the cathode and regenerate CAN.

Summary: This study investigated the use of glycine as a lixiviant for copper dissolution from waste PCBs, and found that glycine concentration did not significantly affect the rate or extent of copper leaching when oxygen was used as oxidant. Increasing temperature improved copper dissolution, while using air as oxidant decreased the copper dissolution due to lower concentration of dissolved oxygen. Using hydrogen peroxide as oxidant did not improve copper leaching. Finally, leaching with 1 M glycine and oxygen at 60 degrees C was proposed as the most feasible condition.

Summary: Metal recycling from waste printed circuit boards (WPCBs) is crucial for resource sustainability. Electrolysis is promising in simplifying processes, improving recycling efficiency, and reducing consumption, while full knowledge on multi metal fate and response mechanism is indispensable for processing complex metals from WPCBs. This study investigated multi metal responses in sulfate-and chloride-system electrolysis and achieved direct copper recovery from WPCBs.

Summary: The study investigated the effectiveness of using a leaching system with hydrogen sulfate ionic liquids to dissolve Cu(II) from e-waste. Results showed that ionic liquids are effective in leaching Cu(II) but require the presence of an oxidant. The presence of H2O2 was identified as the main factor responsible for efficient Cu(II) leaching in this system, as confirmed by ANOVA analysis.

Summary: A novel method for extracting copper and iron from Pyrite cinder was proposed in this paper, and promising results were obtained in the experiments. The maximum copper leaching recovery reached 82.18% under optimized conditions, and a high-quality iron concentrate was obtained subsequently from the leaching residuals through magnetic separation. The leaching process was controlled by mixed diffusion and chemical reaction, with an activation energy of 27.97 kJ/mol.

Summary: Coppermaking from sulfide concentrates typically involves smelting and converting steps. However, in the continuous direct-to-copper smelting process, these steps are combined to reduce energy consumption and costs. Despite its advantages, a disadvantage of this process is the dissolution of copper in the slag, leading to significant recovery costs.
