Quantification of Valuable Metals from E-Waste

E-waste is a growing environmental concern for both developed and developing countries in recent times. Huge quantity of e-waste is generated world-wide each year. In the present work, authors have processed three different kinds of e-waste sources (SMPS, mobile phone & television remote), and while presenting a reproducible technique using chloride leaching to extract the valuable content (e.g. gold, silver) and other elements (e.g. Co, Ni), also presented the comparative study of their observed composition.
