Iron Ore Pellets and Pelletization Process
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) process.

Iron Ore Market Size, Growth & Share | Forecast-2032
Iron ore is the third most abundant element on Earth. Hematite and magnetite are the principal components of iron ore. Iron ore comprises more than 60% iron compounds, most of which are magnetite or hematite. These ores are known as "direct shipping" or "natural ore," as they can be directly fed into the iron-making blast furnace.
