title = "Effect of basicity on ferromanganese production from beneficiated low-grade manganese ore",
abstract = "Indonesia is known to have a large low-grade manganese ore reserve. Nevertheless, it could not be used optimally in producing ferromanganese due to their low Mn/Fe ratio. In this present study, the beneficiation process had been applied to the low-grade manganese ore. Reduction roasting was conducted to this manganese ore at 700°C for an hour and then continued with low-intensity magnetic separation. This process had improved the Mn/Fe ratio from 1.39 to 6.11. The effect of basicity on ferromanganese production from this beneficiated low-grade manganese ore had been investigated clearly in this experiment by using mini submerged arc furnace (SAF). Several basicities for 0.7 and 1.0, was used and it was controlled by the addition of limestone in this smelting process. From this experiment, the ferromanganese containing 60% Mn was obtained from smelting the beneficiated low-grade manganese ore with the optimum basicity 0.7.",
