Cold briquetting of iron ore fines for DRI production ...

Fine and ultrafine iron ores have always been a challenging raw material to use in the blast furnace as well as in alternative ironmaking processes. Despite of having superior iron content than lumpy ores, their handling is very difficult. Traditional techniques like sintering and pelletizing have certain limitations in terms of particle size of fine ores as well as a maximum limit to use
