Production of manganese magnesia sinter using enriched nikopol manganese ore and magnesia-silicate slag from ferronickel production

The industrial introduction of a new production technology for manganese magnesia sinter (7–10% MgO) at PAO NZF is considered. In this technology, the raw materials are enriched Nikopol manganese ore and magnesia-silicate slag (28–30% MgO, 50–52% SiO₂) from the production of ferronickel (15–20% Ni) at Pobuzhsk Ferronickel Works on the basis of imported nickel ore with magnesia-bearing barren rock. Data are presented regarding the microstructure of the sinter, the chemical composition of the phase-mineral aggregations in the sinter, and the mechanical properties of standard and experimental sinter samples.
