The essential parameters affecting the pelletization process of pyrite ash were studied using bentonite as a binder. Experiments were then carried out using bentonite and a mixture of bentonite with calcium hydroxide and calcium chloride in order to make the bentonite more effective.
Even though the use of bentonite in iron ore pelletizing is essential, it is also a problem due to its adverse effects, caused by the impurities introduced with bentonite, on ironsteel economy.
The most common agglomeration technology in the iron ore industry is pelletization with bentonite being the most often used binder. The addition of very small amounts of Alcotac ® CS allows to reduce the dosage of bentonite by about 50% or more without compromising on pellet quality. Depending on the quality of the bentonite and ore, sulfur ...

EFFECTIVENESS OF ORGANIC BINDERS FOR IRON ORE PELLE"nZATION By Larry A. Haas,1 Jeffrey A. Aldinger,2 and Robert K. Zl3 ABSTRACT The Bureau of Mines investigated the use of organic binders as substitutes for bentonite in agglomerating iron ore concentrate. Over 30 organic binders were evaluated at several dosage levels
Jan 01, 2012· The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization:
Iron Ore Pelletizing Bentonite. The need for iron ore pellets is directly connected to the steel production industry. Through the pelletizing process, iron ore fines are converted into spherical pellets, which are then suitable as feed material in blast furnaces for pig iron production.
Our organization involved in providing a quality assured range of Bentonite Ore. It can be widely used for Iron Ore Pelletizing. Which is formulated from finest quality raw and base materials. That is highly preferred in the market due to its perfect composition and cost effectiveness.
The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.
The metallurgical and chemical tests results showed that good quality product pellets can be produced with combined binders when compared with the bentonitebonded pellets. Hence, the suggested combined binders can be used as binder in place of bentonite in iron ore pelletizing without compromising the pellet chemistry.

Nov 26, 2014· 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.
1. Introduction. 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 US3–5 million annually for bentonite.

FLOFORM™ Iron Ore Pelletization FLOFORM™, an alternative Traditionally bentonite is used as binder, but it reintroduces deleterious elements such as silica and alumina. FLOFORM is typically dosed at % prior to balling, about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
Abstract: In this study, sodium, calcium, and mixed bentonite samples were used as binders in the pelletizing fine iron ore concentrate obtained from the Divrigi Iron Ore Concentration Plant in Turkey. In the pelletizing tests, sodium bentonite sample was used as received and after upgrading process.

Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent.
Anew kind of iron ore pellet binder named humic acid modifying bentonite (HAMB) has been developed by the author''s group, which has the advantages of both organic HA and inorganic bentonite. The green pellet strength can be obviously improved by using the HAMB binder.
