Copper recovery from waste printed circuit boards

 · Copper recovery is the core of waste printed circuit boards (WPCBs) treatment. In this study we proposed a feasible and efficient way to recover copper from WPCBs concentrated metal scraps by direct electrolysis and factors that affect copper recovery rate and purity mainly CuSO4·5H2O concentration NaCl concentration H2SO4 concentration and current density were discussed in detail.
