This study investigates the hydrometallurgical recovery of copper and gold from waste printed circuit boards (WPCBs) using a sequential oxidative leac

An investigation into the leaching behaviour of copper oxide minerals in aqueous alkaline glycine solutions

Copper oxide minerals are normally extracted by acidic leaching followed by copper recovery with solvent extraction and electrowinning. However, coppe

B.C. Tanda, E.A. Oraby, J.J. Eksteen

Glycine solutions in an alkaline environment have been shown to be able to leach copper from its oxide, native and sulfide minerals as a copper glycin

Extraction of copper and the co-leaching behaviour of other metals from waste printed circuit boards using alkaline glycine solutions

Huan Li, Elsayed Oraby, Jacques Eksteen

Waste printed circuit boards (WPCBs) are a complicated and valuable fraction of electric and electronic waste. The recycling of them is critical to av
