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 …

Mining

In the processing stage, the mined material is transformed into usable raw material. For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking.
