Sep 29, 2003· Current practice for pelletizing iron ore concentrates was developed in the 1950s. At that time, bentonite clay became established, and remains today as the most acceptable binder due to its combination of effectiveness and relatively low cost. Dry bentonite is added to iron ore concentrate filter cake, which contains approximately 10% moisture.
Jan 01, 2012· 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.
typical dosage of bentonite is 0.66% of the moist (typically 10% moisture) iron ore concentrate filter cake (Ripke and Kawatra, 2000). The dosage of sodium bentonite needs to be kept as low as possible because pellets containing more bentonite cost more to produce and contain higher silica content. This gives the industry an incentive
Mar 21, 2015· Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation.
