increasing the durability of pellet iron ore

Improving reducibility of iron ore pellets by optimization

induration. A study with calcium hydroxide in iron ore pellet [ 5] showed that with increase in calcium hydroxide, amount of FeO increased because secondary Fe 2 O 3 reacted with CaO forming ferrite which helped in decomposition of Fe 2 O 3 again to FeO. Thus, with increase in amount of calcium hydroxide, hematite phase decreases due to

Iron Ore Pellet an overview ScienceDirect Topics

In this route of iron making, the use of noncoking coal or natural gas is made as reductant for iron ore. The oil is used for heat hardening of iron ore pellets which is generally exploited by gas-based DRI plants. The coal-based DRI units generally require lump ore which need some electrical energy during crushing and sizing operations.

Introduction to Iron ore Pellets and Pelletizing processes

Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter

Pelletizing Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of
