Manganese Carbonate Ore Scientific.Net

Magnetic separation behaviors and magnetic properties of raw manganese ore and roasted manganese ores were analyzed. After reduction by coal and biomass fuels, the manganese ores demonstrate a new Mn-Fe oxide phase, showing obvious mixed magnetic behaviors of ferromagnet and paramagnet, and the magnetic susceptibilities of roasting ores rapidly increase to almost two orders of magnitude in comparison of the raw ores.

2014-11-22  The grade of Mn for the roasted ore could only be concentrated to 15.49% with a recovery of 66.67%. Therefore, it is concluded that the low-grade manganese ores with antiferromagnetic and paramagnetic (or diamagnetic, but not strongly ferromagnetic) properties could be efficiently beneficiated via high-intensity magnetic separation.

Extraction of manganese from low-grade manganese

1982-1-1  With H2SO4 only (147.0 g/l), 2.13% manganese was extracted with untreated ore but 97.7% manganese was extracted with a negligible amount of iron when the reduced ore was used. With pickle liquors of any of the compositions (a, b and c) more than 95% manganese was extracted in the case of reduced ore, but the same ex- traction efficiency was observed for the untreated ore with pickle liquor

2021-5-1  As observed in Fig. 12(a), as the manganese ore roasted at a lower temperature range of 900– 1200 °C, a certain amount of hematite (in white color) still exists in the briquettes owing to the slower solid reaction velocity of manganese and iron oxides. When the temperature exceeds 1200 °C, three main phases of manganese ferrites (with incanus color), silicates (with light gray color) and

Kinetics and Mechanism of Low-Grade Manganese

2019-4-15  Although manganese oxide minerals of the ore were not carburized at the experimental conditions, the manganese associated with iron oxides was carburized to cementite ((Fe,Mn) 3 C), and it was accompanied with CO gas release. Higher rates and extents of manganese oxides reduction were obtained with increase in temperature; however, the simultaneous formation of manganese silicates
