In order to protect the environment and preserve the concept of sustainability, intensive work has been done in recent years on the development of recycling technologies. Among the numerous components of discarded electronic devices, printed circuit boards stand out for their high content of precious metals. This paper provides an overview of previous research in the field of hydrometallurgical process, such as gold recovery from waste printed circuit boards. Therefore, solutions containing cyanides, thiosulfates, thiourea, halides, and aqua regia are used for gold leaching from waste printed circuit boards. However, due to the high toxicity and possible side effects on the environment and human health, research has focused on the use of non-cyanide solutions in recent years. info:eu-repo/semantics/conferenceProceedings Proceedings :International Conference Ecological Truth & Environmental Research (29 ; 2022 ; Sokobanja) str. 387-392 2022 Recycling gold from waste printed circuit boards application/pdf 838466 bytes https://unilib.phaidrabg.rs/o:5242 cobiss:134590729 ISBN: 978-86-6305-123-2 Keywords: waste printed circuit boards, recycling, leaching, gold, non-cyanide solutions. eng All rights reserved
