• Mechanochemical modification of electrolytic manganese

    2021-12-20 · The high content of ammonium sulfate (ammonium nitrogen) and soluble manganese in EMR are the main reasons that limit the large-scale resource utilization and the environmental hazards of the EMR (Mallick et al., 2006). In an attempt to solve this critical issue, this study CaO was added to the EMR and then mechanical ball milling, the ammoniumStudy on Preparation of Ammonium Sulfate by Solid ,Ammonium sulfate was prepared by solid-phase ball milling from phosphogypsum and ammonium bicarbonate as the raw material.The technology of the preparation was optimized through orthogonal experiments;the phase compositions of product was revealed by XRD analysis;and the reaction mechanism was also discussed.The results showed that the optimum solid-phase ball
