PROCESSING AND PELLETIZING OF LOW GRADE MALAYSIAN IRON ORE HATEM M. BELHAJ UNIVERSITY SAINS MALAYSIA 2008 . 2 PROCESSING AND PELLETIZING OF LOW GRADE MALAYSIAN IRON ORE by HATEM M. BLHAJ Thesis submitted in fulfillment of the requirements for degree of Master of Science
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
Malaysian low-grade iron ore was taken as the raw material in this experiment. Ammonia decomposition over iron ore medium were studied at temperature of 500-700°C. The nitriding potential of ore was also studied. Keywords: ammonia decomposition, hydrogen, low grade iron ore, ammonia conversions and nitriding potential. INTRODUCTION
