Low-grade ore. Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite. The ore may be easily beneficiated by

UTILIZATION OF MALAYSIAN LOW GRADE IRON ORE AS MEDIUM FOR AMMONIA DECOMPOSITION Nur Ezzah Faezah Othman, Hadi Purwanto and Hamzah Mohd Salleh Faculty of Engineering, International Islamic University Malaysia, Jalan Gombak, Gombak, Selangor, Malaysia E-Mail: [email protected] ABSTRACT Hydrogen has been regarded as the new energy source due to

May 09, 2020 Raw iron ore has to be purified for use. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. High-grade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%. Low-grade iron ore includes all mixtures below

Therefore, research on utilization of low grade iron ore to produce quality raw material will play a key role in future—a fact acknowledged by the iron and steel industry. Iron ore from the same mine may look the same, but its response to beneficiation technique can vary enormously. For that matter, each source of iron ore has its own peculiar mineralogical characteristics and requires

1/10/2009· Exploitation of these iron minerals needs to take a different approach, using fewer process steps than are required for conventional ironmaking. Results are presented showing that it is possible to produce metallic iron directly from low-grade ores. The metal is in a form that can be easily separated to produce a high-grade iron product, and
