Resource Utilization of the Electrolytic Manganese Residue in Unfired Bricks: Pretreatment, Strength Enhancement, and Microwave Absorption Properties.

ABSTRACT: The long-term accumulation of electrolytic manganese residue leads to pollution issues related to NH₄ ⁺-N and Mn²⁺. Although various methods exist to address the pollution caused by NH₄ ⁺-N and Mn²⁺, existing hazard-free treatment methods do not consider the subsequent utilization of the electrolytic manganese residue. Meanwhile, resource recovery methods face challenges due to the complex salt structures present in electrolytic manganese residue. This study introduces BaCO₃ to achieve the phase reconstruction of the complex salt structure. The results indicate that the addition of BaCO₃ effectively promotes the reconstruction of complex salt structures. The leaching toxicities of C-(NH₄
