Towards sustainable metal recovery from e-waste: A mini review

Abstract

E-waste seems to be the major concern in present day technological world. It is the high time to treat the e-waste and to prevent various adverse effects from e-waste pollution. Heavy metals present in the e-waste raises the concern to be worried. Various research and studies have been focused and developed on e-waste recycling. Apart from this, heavy metal and valuable metal recovery from various e-waste seems to be economical. For the metal leaching process various leaching methods are involved. In this review, effects of e-waste, its composition and various methods available for treating e-waste and heavy metal leaching like chemical leaching and bioleaching and factors affecting the leaching mechanism have been reviewed.
