  • Iron Ore Pelletizing Process: An Overview

    The iron ore pelletizing process consists of three main steps: 1 Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2 BallingprocessProcess Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F))ppt in iron ore pellet reduction process
