Zaporizhzhya Iron Ore Plant Private joint stock company with foreign investments. Main products: sinter and open-hearth ore ... Agglomeration and open-hearth ore is mined at the ZZRK. Of the total production, about 95% is sinter ore, which contains 61% iron. Open-hearth ore contains 54-58% of iron.
However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must …
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 …
Historically, bentonite has been used in the agglomeration process in North American iron ore plants. In 1986, Eveleth Mines replaced bentonite with Peridur, a carboxy methyl cellulose organic binder used in conjunction with 1% limestone. Since May of 1993, Allied Colloids` Alcotac FE8 has been used by Eveleth as the replacement for …
