title = "Beneficiation of two different low-grade Indonesian manganese ores to improve the Mn/Fe ratio",
abstract = "The beneficiation of two different low-grade manganese ores had been done by gravity separation and reduction-roasting process followed by the magnetic separation to improve their Mn/Fe ratio. The effect of particle size and temperature of reduction-roasting in this beneficiation process had been investigated clearly. XRF and XRD analyzer were used to characterize the as-received and beneficiated of these low-grade manganese ores. From the result, the manganese oxide in the form of pyrolusite (MnO2) was easier to beneficiate for enhancing the Mn/Fe ratio than in the form of pyroxmangite (MnSiO3) and grossular manganoan (Ca1.3Mg0.1Mn0.8Fe0.8 Al2 (SiO4)3. The optimum beneficiation resulted from the reduction-roasting process of low-grade manganese ore in -40+60 mesh at temperature 700°C followed by the magnetic separation process. It had improved the Mn/Fe ratio of this low-grade manganese ore from 1.39 into 4.0.",
