ITmk 3 Process of making Iron Nuggets – IspatGuru
ITmk3 process produces high purity granular iron (Iron nuggets) by using iron ore fines and non coking coal. The process is distinctive with reduction, carburizing melting and slag separation (Fig 3). The process occurs at lower temperatures (around 1350 deg C) and hence different from conventional iron making by blast furnace (BF).
