Adsorption removal of Mn²⁺ and NH₄⁺–N from electrolytic manganese metal wastewater by modified phosphate ore flotation tailings

Abstract

Electrolytic metal manganese wastewater (EMMW) is industrial wastewater produced in the process of producing electrolytic metal manganese, which contains Mn2+ and NH4+–N pollutants.

A Critical Review on Approaches for Phosphorus Ore Flotation Tailings Treatment and Disposal Technology: Environment Properties, Comprehensive Utilization, and Resource Utilization

“…Deng et al 108 used an electric field and POFTs for Mn 2+ and NH 4 + -N removal in electrolytic manganese residue leachate (Figure 4). Wu et al 109 used modified POFTs to remove Mn 2+ and NH 4 + -N from electrolytic manganese metal wastewater. Roasting POFTs can also effectively treat phosphorus-containing wastewater, which provides an effective technological pathway to the resource utilization of POFTs.…”
