▎ 摘　　要

NOVELTY - Recovering metal involves (a) mixing a material prepared from e-waste with a conductive additive to form a mixture, (b) applying a voltage in one or more voltage pulses across the mixture to recover metal from the material for a duration period, and (c) collecting the recovered metal. USE - Recovering metal e.g. rare earth element, precious metal and toxic heavy metal (all claimed). ADVANTAGE - The method enables to recover precious metals and other metals from electronic waste (e-waste) in a solvent-free and sustainable process, and remove hazardous heavy metals in electronic waste within one second. The method is highly efficient and low-cost synthesis of nanomaterials is the prerequisite for their commercial applications. The high temperature enables the evaporative separation of precious metals from the supporting matrices, with the recovery yields greater than 80% for Rh, Pd, Ag, Ir, Ru, and Pt, and greater than 60% for Au. The heavy metals are highly toxic including Cr, As, Cd, Hg, and Pb, are also removed, leaving a final waste with minimal metal content, acceptable even for agriculture soil levels. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for system for performing the method of recovering metal.
