In the production of iron ore concentrate pellets, binders are required to improve pellet green strength. The most popular binder for this purpose is bentonite clay, which is added at a rate of approximately 0.5–1.0% by weight of moist concentrate. Bentonite is a significant cost item in iron ore ...
Iron ore pelletization plants in the United States used approximately 612,000 metric tons of bentonite as a binder to produce iron ore concentrate pellets in 2000 (Virta, 2001). It is a major cost item, with individual plants spending US$3–5 million annually for bentonite.
Iron Ore Pellets and Pelletization Process Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.
Effects of bentonite fiber formation in iron ore pelletization. In the production of iron ore concentrate pellets, binders are required to improve pellet green strength. The most popular binder for this purpose is bentonite clay, which is added at a rate of approximately 0.5–1.0% by weight of moist concentrate.
⋅ Iron ore pelletization with bentonite binder works by a different binding mechanism than with FBB. Bentonite is a physical binder, while FBB is a pozzolanic binder. ⋅ Iron ore concentrate pellets produced with up to 50% of the bentonite replaced by fly-ash exceeded minimum industrial specifications for dry compressive strength.

Bentonite is a significant cost item in iron ore pelletization, and also contributes undesirable amounts of silica to the finished pellets. If the binding effectiveness of bentonite is increased, it will be possible to reduce the bentonite dosage, resulting in significant cost savings while producing higher quality, lower silica pellets.
Nov 26, 2014 Iron Ore Pellets and Pelletization Process Pelletizing of iron ore was A mixer is used for the addition of the binder (bentonite or organic Alcotac® FE14-Mining Solutions-BASF employed in the preparation of organic binders for the iron ore pelletisation Fired pellet quality is comparable to bentonite pellets, however the particular.
compared with the bentonite-bonded pellets. Hence, the suggested combined binders can be used as binder in place of bentonite in iron ore pelletizing without compromising the pellet chemistry. KEYWORDS: iron ore pelletizing, bentonite & organic binder, boron compounds, colemanite, chemical and metallurgical properties.
Bentonite is a predominant binder used in iron ore pelletization. However, the presence of a high content of silica and alumina in bentonite is considered undesirable for ironmaking operations. The objective of this study was to identify the alternatives of …
Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
