Recycling silver and copper from rub out copper wire plated with silver

Abstract

Recycling of secondary raw materials recently become more interesting , mainly due to reduced quantities of waste and price of waste water treatment. Aim of this work was recycling and production of copper ana silver from rub out copper wire plated with silver. Silver and copper high purity (99,99%) from rub out copper wire realized by combining pyro-metallurgy, electro-metallurgy and chemical treatment in laboratory and pilot production plant in Institute of Mining and Metallurgy Bor.

U novije vreme povećan je interes za recikliranjem metala čime se smanjuje količina otpada kao i troškovi tretiranja otpadnih voda. Cilj ovog rada bio je da se iz istrošene posrebrene bakarne žice valorizuju srebro i bakar, a da se nečistoće, kao što su olovo, kalaj, antimon i kadmijum uklone. Srebro i bakar visoke čistoće (99,99 %) iz istrošene žice dobijeni su kombinacijom pirometalurških, elektrometalurških i hemijskih postupaka u laboratorijama i poluindustrijskim postrojenjima Instituta za rudarstvo i metalurgiju u Boru.
