Review of organic binders for iron ore concentrate agglomeration
Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make iron ore concentrate pellets, but it is …

Review of Organic Binders for Iron Ore Agglomeration
Introduction Iron ore pellets are one type of iron-rich, intermediate product used during primary iron and steel making. During pellet production, fine-grained iron containing minerals are liberated from lowgrade ores, concentrated, and agglomerated into round balls that are thermally hardened to form "pellets". Pellets are then transported to Blast Furnace or Direct Reduction operations ...

PROCESS FOR PRODUCING AN IRON ORE FINES …
[0008] Pelletizing is the most recent agglomeration process and was the result of the need to use fine concentrates of magnetite from certain iron ores. Iron ore pellets are produced by agglomeration of particles of less than 45 mm in size, forming pellets of from 8 to 16 mm, in disc or rotating drum. The material to be agglomerated must have a ...

Iron Ore Pellets and Pelletizing Processes
1. Pelletizing is a process that involves mixing iron ore fines with additives, shaping them into spherical pellets, and hardening the pellets through firing. This converts iron ore fines into uniform pellets that can be charged directly into a blast furnace. 2. There are four main stages to pellet production: raw material preparation, green pellet formation, pellet induration through heating ...
