In the present study, a model of closed-loop recycling of copper from PCBs is demonstrated, which involves the sequential application of bioleaching and electrowinning to selectively extract copper. This approach is proposed as part of the solution to resolve the challenging ever-increasing accumulation of electronic waste, e …

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 information may be used as a high-level selection guide to assist with identifying a cost-effective copper electrowinning circuit design for a specific production rate. The data was validated and compared with existing copper electrowinning cellhouses around the world that typically install no more than 84 cathodes per cell. Keywords: ...

Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably). Copper ores are usually copper oxides ...
