Abstract
In the process of iron making reduction of iron ores to metallic iron is done by coke which acts as a reluctant. As, both the reduction process, conventional blast furnace and DRI technologies are driven by the Boudouard reaction, so there is a probability for substituting of coal/coke with biochars, which could provide a good source of carbon and energy for the reduction. Hence, the utilization of bio char can become an emerging technology and better option for replacing coking coal for metallurgical purposes. This study includes characterization and comparative study of reduction of Iron ore pellets and fines using Wooden Bark Char (WBC) as one of the biomass waste. From the results, reduction of iron-ore fines with comparable ratios with WBC gives the maximum degree of reduction than reduction of iron-ore pellets. Thus, WBC can play an important role in behind the premium quality of coking coal reserves.
