US3598569A - Iron ore pelletization

Iron ore production in 2019 is estimated at 2.850 billion tonnes, and according to conservative forecasts, global iron ore production is expected to reach 3.119 billion tonnes by 2028, an annual increase of only 0.9%. In contrast, global pelletizing capacities are expected to increase by 5.5 % per annum until 2025.Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a "green" pellet or ball, which is then dried and hardened in a separate step, usually by heating. Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum.
