    摘要: Disclosed is a system for removing metals from waste, particularly electronic waste (or “e-waste”). The process generally includes the steps of dissolving at least some of the metals from the wastein a nitric acid bath 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 reclaim more preferably NOx gas for the regeneration of nitric acid, which is recycled for use in the metal reclamation system.

    摘要: Recovery of nonferrous, rare and precious metals from sulfide minerals and concentrates is described. The hydrometallurgical method of sulfide minerals and concentrates processing, involving sulfide minerals oxidation in aqueous medium using nitrogen oxides, provides that the sulfide materials containing slurry are subjected to oxidation of the sulfide which is realized under controlled conditions of the slurry acidity. Constant neutralization of sulfuric acid formed as a result of the sulfides oxidation is provided. The sulfuric acid is neutralized to acidity level, at which no formation of elementary sulfur occurs, while natural or artificial substances, such as CaC03, MgC03, Ca(OH)2, CaO, NaOH, CaHP04 etc., are used as acidity neutralizers. Oxidation of sulfide minerals is realized under agitation. Oxidation is realized in the range of 20-90° C., mainly in the range of 65-85° C. The liquid-to-solid ratio varies from 1:1 to 5:1, depending on effectiveness of the required precipitate formation and proceeding of the oxidation.
