| Abstract |
In a race to save the planet of its rapidly depleting natural resources, the use of Secondary Raw Materials (SRMs) as replacements in several processes is currently intensively pursued. In fact, this is currently one of the European Union (EU)'s mandates. Valorization of SRMs is consistent with circular economy, where resource efficiency is maximized for the benefit of both businesses and the environment. In line with this mandate, this paper focuses on investigating process phenomena related to hydrometallurgical recycling of Electric Arc Furnace (EAF) dust. In the experimental study, selective dissolution of zinc and other metals is investigated to acquire a recyclable leach residue. Based on the experimental and theoretical investigations, zinc could be extracted from the EAF dust and a recyclable leach residue produced, having chemical composition suitable as a feed material into electric arc furnace. |
