UTILIZATION OF MALAYSIAN LOW GRADE IRON ORE AS

2015-12-21  The low grade ore used in this present study which was taken from Chini area from Pahang state Malaysia was employed as the raw material. Mineral composition of the original ore consists of iron oxide species of 58.1% with the existence of other gangue minerals such as alumina, silica, mangan oxide, calcium, vanadium and titanium are shown as tabulated in Table-1. Ammonia decomposition using low grade iron ore as medium took place in an 8mm fixed bed reactor. The iron ore was introduced into quartz tube and dehydrated at 400 °C. Dehydration of iron ore was conduct to remove the combine water present in the original ore. Thermal gravimetry analysis (TGA) was used to analyse the change in weight loss of original iron ore
