Abstract: The rapid growth of the world's population and the permanent need of modern consumer society for more energy-efficient products, have led to the accumulation of electronic waste. 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.
