Paper Title
REDUCTION OF IRON ORE BY CHARCOAL UNDER MICROWAVE IRRADIATION
Abstract
Iron sand is a source of iron ore containing hematite, magnetite and other impurities which is raw materials for
ferrous materials production. Recently, there are so many extractive metallurgy process that was developed. One of these
processes was using microwaves irradiation as power sources in iron ore reduction process . The concept of iron ore reduction
by microwave heating is proposed of this paper. A microwave would be operated in various of power supply and irradiation
time to get the optimum reduction process indicated by large amount of Fe content. Then it was characterized using X-Ray
Diffraction (XRD) to identify chemical compound and phase transformation that occurs after reduction process, X-Ray
Fluorescence (XRF) to determine amount of element and increasing level of Fe content, Scanning Electrone Microscophy
(SEM) to observe morphology of the sample. this study concluded that the highest Fe content is 81.67% yield by 60 minutes
microwaves irradiation in power supply as high as 3000 watt.
