Electric arc furnace dust (EAFD) of ferromanganese production units contains various elements including manganese and iron, necessitating efficient separation methods. This study aimed to investigate a hydrometallurgical route based on solvent extraction for the selective separation of manganese from EAFD leach liquor. The leaching process produced an aqueous feed rich in manganese and iron, leading to extraction tests utilizing D2EHPA, Cyanez 272, Cyanez 302, and their mixtures. The research analyzed the synergistic effects of these extractants, finding that adjustments in the extractant ratios significantly influenced the separation efficiency. Notably, the most favorable separation factor was achieved with a 15:5% v/v mixture of Cyanez 302 and D2EHPA. Furthermore, the impact of different aromatic and aliphatic diluents on extraction efficiency was assessed. The results demonstrate the viability of solvent extraction techniques in enhancing the purity of manganese by effectively separating it from iron in the context of EAFD recycling.
