Utilization of EFB-derived biochar in sintering of iron ore has been conducted in this
work with regards to the porosity of iron sinter. EFB has been heated up in argon atmosphere to
450ºC in order to produce biochar. In the present work, the sintering process was conducted at
1150ºC with variations of biochar content from 5% to 10%. In this case, the apparent density for
iron sinter shows significant decrease as the biochar addition increase. The porosity of iron sinter
showed a gradual increment from 5% to 7.5% and escalated at 10% biochar content. The results
of porosity and apparent density were in line with the micrograph of iron sinter
