Iron Ore Characterization Techniques in Mineral Processing
Through these methods, hematite and goethite, iron oxide and iron hydroxide respectively, were determined to be the major components of the iron ore sample studied. These analytic tools also confirmed the higher levels of hematite as compared to goethite. Infrared radiation, like X-rays, is important in the chemical characterization of ores.This paper examines the effectiveness of the method for producing synthetic rutile from ilmenite through pre-oxidation and reductive leaching of pre-oxidized ilmenite in hydrochloric acid.Production of synthetic rutile from tin ore beneficiation
