Management of Iron Ore Beneficiation Process Using Magnetic Separator in Bonto Cani District, Bone Regency, South Sulawesi Province

Abstract

Iron ore is the second most-weighted metal on earth. To meet the needs of life and the rapid development of technology, the availability of raw materials in the form of metal minerals in large quantities is required. So the appropriate quality of iron ore is needed for use, in this case the intent and purpose of the research is to know the process of obtaining iron ore concentrate using magnetic separator method and know the percentage of iron ore content and recovery most optimally with magnetic concentration using magnetic separator. Based on the literature study of several iron ore journals from Tanjung District Bontocani Regency Bone South Sulawesi Province, it is known the process of obtaining concentrate and percentage levels and recovery of iron ore based on data supporting previous research namely the XRF value of Fe2O3. The acquisition of concentrates using magnetic separator methods is carried out by means of magnetic separation performed on each sample that has been grouped according to the fraction of the grain size. Magnetic separation results in concentrate (magnetic) products and tailings (non-magnetic) products. The percentage of iron ore content and recovery using magnetic separators produces the highest percentage of Fe2O3 levels found in fractions (150 mesh) with a value of 85.429% and the highest percentage recovery rate obtained at fraction (200 mesh) with a value of 96.70%.
