Current Trends in Leaching of Noble Metals from Electronic Waste

Warianty tytułu
Bieżące trendy w ługowaniu metali szlachetnych z elektroodpadów
Języki publikacji
Metale szlachetne są wykorzystywane w przemyśle elektrycznym i elektronicznym ze względu na ich doskonałe przewodnictwo elektryczne, niską rezystancję elektryczną i odporność na korozję, mimo że pierwiastki ziem rzadkich zaczęły częściowo zastępować metale szlachetne w przemyśle elektronicznym. Dlatego duża liczba e-odpadów zawiera znaczną ilość metali szlachetnych, szczególnie złota, srebra i palladu. Recykling metali szlachetnych z odpadów elektronicznych jest zatem bardzo ważny. Na przykład zawartość złota w zużytych płytkach obwodów drukowanych jest 35-50 razy wyższa niż zawartość złota w rudach. Recykling metali szlachetnych z elektroodpadów, w tym ługowanie, oczyszczanie oraz odzysk i rozdział, jest drugim etapem po odzysku metali nieszlachetnych. Najczęściej do ługowania metali szlachetnych stosowane są cyjanek, tiomocznik i tiosiarczan, ze względu na powstanie stabilnego kompleksu metalu. W niniejszej pracy przedstawiono przegląd różnych rozwiązań i roztworów wykorzystywanych do ługowania metali szlachetnych z odpadów i/lub rud. (abstrakt oryginalny)
Noble metals have been used in electric and electronic industries due to their excellent electrical conductivity, low contact electrical resistance and corrosion resistance, even though rare earths have started partially replacing precious metals in electronic industry. Therefore, a large number of e-waste contains significant amount of precious metals, particularly gold, silver, and palladium. It is of importance to recycle precious metals from e-waste. For instance, the gold content in waste printed circuit boards is 35-50 times higher than gold ore. Extraction of noble metals from waste electronic and electrical equipment (WEEE), including leaching, purification and recovery, is the second stage after the recovery of base metals. The most common leaching reagents for precious metal leaching include cyanide, thiourea and thiosulfate because of the stable metal complex formed. This paper presents a review of various solutions using for noble metals leaching from wastes or ores. (original abstract)
