%X In this paper we report synthesis and characterization of hausmanite (Mn₃O₄) manganese ores nanoparticles from West Sumatera deposit by High-Energy Milling method. The synthesis was carried out using sintering temperature variation of 26 °C, 600 °C, 700 °C, 800 °C, 900 °C, and 1000 °C and milling time of 0 hours, 2 hours, 4 hours, 8 hours and 10 hours. Characterization is done by using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). XRF test results showed that the manganese content was 84.139%. The Hausmanite phase was obtained when the sample was sintered at 700 °C. The crystal structure of the Hausmanite phase is tetragonal. We obtained the hausmanite nanoparticles with homogeneous size distribution could be synthesized at 8 hours of grinding time. The size of the nanoparticles produced is 90.50 nm.
