Lupine Publishers | Bioleaching of Basic Metals from Electronic Waste PCBs
Abstract
E-waste is an emerging problem that has to be attending worldwide. The best way for E-waste management is recycling. Bioleaching is a novel method to extract metals from E-waste. In this research, bioleaching of Cu and Ni from an E-waste sample was examined using acidophil microorganisms. Different kinds of E-waste were purchased; the sample size reduced to lower than 100 microns. Acidithiobacillus ferrooxidans was adapted to the 15 g/l of the E-waste sample. Eh, pH, bacterial count, and metal recovery were followed in a period of 25 days. By using inductively coupled plasma optical emission spectroscopy (ICP-OES) identified Cu and Ni were recovered respectively 99% on 11th day and 98% on 14th day. The results of field emission scanning electron microscope (FE-SEM), Fourier transform infrared spectrometer (FTIR), and X-ray diffraction before and after bioleaching emphasize the great efficiencyofbioleaching.
