Selection of Feasible Leaching Method for Recovery of Heavy Metals from E-Waste Using Analytic Hierarchy Approach
Author(s): Garima Minocha, Vinita Khandegar* and Sanigdha Acharya
Amount of e-waste is increasing tremendously over the years, from almost getting doubled each year. 40% e-waste
consists of many metals and precious metals. The rapid growth in technology development is alarming, as a result
more and more e-waste is generating. This leads to myriad problems for handling or management of e-waste.
Traditional methods of disposal of e-waste such as landfilling, composting and incineration are major threat to the
environment and life. In this study recovery of metals through hydro-metallurgical process such as thiosulfate (M1),
iodide (M2) aqua-regia (M3) and thiourea (M4) leaching methods were compared in terms of economic feasibility,
environmental impact and reagent reuse in order to find out a feasible leaching method using Analytic Hierarchy
Process (AHP). The selection of feasible leaching method has been performed by applying t.. View More»
