Are Iron Ore Pellets Better Than Sinter

Nov 26 2014 Iron Ore Pellets and Pelletization Process Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production For the pelletizing of iron ore there are two main types of processes namely the straight travelling grate (STG) process and the grate kiln (GK) processIron ore sinter and pellet Sep globally around two billion tonnes of iron ore average is used in the form of lumpssinterpellets to produce steel however the reserves of highgrade ore are depleting rapidly due to which the adoption of beneficiation technologies such as sintering and pelletizing to utilise fine ore and lowgrade ore is attracting heightened
