This research was carried out to recover valuable metals from the electronic waste (e-waste). E-waste samples were crushed and thermally activated under 450 degC within 1 hour. The optimal temperature of the thermal treatment, at which all organic phases are removed and metal's forms turned into oxides was determined. Leaching of thermally activated material using EDTA at room temperature, pH 7 for 1 hour resulted in greater than 95 % extraction of lead. Non-ferrous metals were extracted at 85 degC with a leaching solution of 2 M H2SO4 which resulted in recovery of more than 98 % of copper within 3 hours. |
