title = "The optimization of Sumbawa manganese ore beneficiation using response surface method (RSM)",
abstract = "The beneficiation of manganese ore from Sumbawa, West Nusa Tenggara, Indonesia has been carried out by leaching method using sulfuric acid (H2SO4). The effects of sulfuric acid concentration, leaching temperature, and reaction time were optimized. The leaching parameters were set based on Box-Behnken Design and optimized using Response Surface Methodology (RSM). The beneficiation product was prepared for the synthesis of lithium manganese oxide (LiMn2O4) that will be applied as lithium ion battery cathode material. X-Ray Flouroscense (XRF), X-Ray Diffraction (XRD) and Atomic Absoption Spectroscopy (AAS) were performed for characterization of manganese ore and lithium manganese oxide that obtained. The optimum of manganese ore leaching yield was 79.57%. The optimum yield was produced by leaching of manganese ore in sulfuric acid 2.5 M, leaching temperature of 70 °C and leaching time of 9 hours.",
