Eco-Friendly Metal Recovery from E-Waste by Ovijit Das is a document available to read on EtoBox.
This document summarizes a study on using a ball milling process to recover valuable metals like copper, palladium, and silver from e-waste scraps. The researchers found that co-milling the e-waste with a mixture of K2S2O8 and NaCl produced soluble metallic compounds that benefited subsequent leaching. Over 99% of copper and 95% of palladium could be recovered from the e-waste particles within 15 minutes using a dilute HCl solution. Silver was concentrated in the leaching residue as AgCl and then recovered
