| 520 | |a In order to meet the demand for domestic steel, mini blast furnace iron-making projects are on the rise. However, Malaysia only has low-grade iron ore instead of commercially high-grade ore as raw materials. The use of low-grade ore will cause in extra energy consumption to release water content in low-grade ore. On the other hand, Malaysia possesses high amounts of waste biomass, which may be utilized as an energy source. This research focuses on the treatment of low-grade iron ore by using waste biomass. The ore was preheated at 400⁰C for one hour to release crystalline water by transforming the goethite compound to hematite. The dehydration process resulting nano pores inside the iron ore which is extended to generate cracks. The dehydrated iron ore is high porosity because of all crystalline water has been released. In this experiment, the iron ore was treated under biomass treatment in the vertical electric tube furnace containing a quartz tube. The heating process was conducted in an inert atmosphere with 15 minutes constant heat. X-ray diffraction analysis confirmed that the iron ore was reduced to magnetite and wustite from hematite at the temperature of 600⁰C and 1000⁰C, respectively. Subsequently, scanning electron microscope observation showed the presence of carbon particles on the iron ore surface after the biomass treatment. The carbon particles were produced from liquid tar during biomass gasification. Based on the results revealed, the waste biomass is a promising energy source to produce pre-reduced iron ore from low-grade iron ore. It will also reduce carbon dioxide emission by replacing a part of fossil fuel or coke in the iron-making process by using pre-reduced iron ore deposited with carbon particle. The product of this process will be used as raw material for iron-making since its iron content is higher than in the original form, 57% of iron and deposited carbon that can produce a reductant agent as well. | ||
