Abstract
The present investigation aims at detailed characterization and beneficiation of the low-grade goethitic ore deposit of Gua iron ore mines from Jharkhand. The main purpose of this study is to determine the chemical and mineralogical properties for its utilization for economic purpose. Chemical composition of iron ore used in the present study comprises of 56.54% Fe, 5.71% silica, 5.18% alumina and 6.62% LOI, and further characterization studies such as X-ray diffraction, microscopic study, Fourier transform infrared spectroscopy, TG–DTA have been carried out to ascertain different minerals. After completion of characterization studies, an attempt has been made to beneficiate the low-grade iron ore fines by selective flocculation using amylopectin as a flocculant and using sodium silicate as a dispersant. Flocculation experiments have been performed by varying dosage of amylopectin and sodium silicate at a pH of 10. From the studies, it is possible to enhance the grade and recovery to 63.66% and 83.33%, respectively.
