Efficient Recovery of Cu from Wasted CPU Sockets by Slurry Electrolysis

In order to maximize the reuse of used electronic component resources, while reducing environmental pollution, Cu metal was recycled from wasted CPU sockets by reformative slurry electrolysis method. However, influences on regulation recovery rate and purity waste slots, electrolysis, has not been systematically elucidated in previous studies. this work, effects H2SO4 concentration, density, NH4Cl current reaction time, were researched systematic experimental methods. The results showed that elements mainly present as powders cathode, rather than electrolyte. Moreover, metallic cathode powder consisted mostly small amounts Sn Ni. up 96.19% 93.72%, respectively, with optimum conditions being: an concentration 2 mol/L, density 30 g/L, 90 80 mA/cm2, time 7 h. Compared studies, recovered experiment powder, which more convenient for subsequent processing. Meanwhile, effectively improved. This is important guideline application recovery.
