Abstract

Disclosed is a process and system for removing metals from waste, particularly electronic waste (or "e- waste"). The process generally includes the steps of dissolving in nitric acid at least some of the metals from the waste and then causing at least some of the metals to precipitate as metal oxides and/or metal nitrates. The system can include multiple tanks or locations for dissolving metals and/or precipitating metals, preferably as metal oxides or metal nitrates. The process and system can also reclaim NOx gas released from the acid bath for the regeneration of nitric acid.
