Recovery of precious metals from electronic waste and spent catalysts

Gold and silver were selectively recovered from copper anode slime (from e-waste smelting) by NaClO 3-NaCl-H 2 SO 4 solution. By controlling the concentration of H + (1.0 mol/L) and Cl − (0.02 mol/L), the leaching yield of gold could reach 98.1%, and the impurities (e.g. Ag and Pb) were hardly leached out ( Ding et al., 2017 ).
