Dec 01, 1995 articleosti_129112, title Organic binders for iron ore pelletization and steelmaking, author Karkoska, D and Sankey, E and Anderson, R, abstractNote 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.
aromatic structure are the best for organic binders of iron pellets. Two kinds of organic binders are synthesized and prepared on the basis of the investigations and they are found to be effective for pelletizing of iron ore concentrates. One of them has been used in commercial production of iron ore pellets in China. 2003 Elsevier B.V.
In pelletizing, iron ore, water and a binder are balled in a mechanical disc or drum to produce agglomerates. Bentonite is the most widely used binder. However, it is considered as an impurity due...
Jan 01, 2015 While commercial usage of Peridur in one Vale pellet plant was reported (Kater and Steeghs, 1984, Jiang et al., 1996, Eisele and Kawatra, 2010), no further reports were found on the commercial usage of organic binders until recently, namely, one of the Cliffs grate-kiln pellet plants was using 100% organic binder to replace bentonite .
Jan 25, 2016 At present, in China, bentonite accounts for 3% of the composition of iron ore pellets. If this proportion can be reduced to 1%, then the grade if the finished pellet will increase by 0.6%, Lei explained, adding that his team was developing a new binder that can reduce bentonite usage to 1-1.5% of iron ore pellets.
Binders are used to make the moist ore plastic so that seeds are nucleated and pellets grow at a controlled rate. The binder holds the green pellet together until strong bonds are formed in the induration process where the agglomerates sinter together at temperatures of around 1300C. Bentonite was the first binder used and is still employed today
Iron Applications. Alcotac organic binders for the iron ore industry. In iron ore pelletization a significant portion of bentonite can be replaced by adding Alcotac FE or CS grades at a very low dosage thus significantly reducing the level of unwanted impurities. As higher quality ore deposits are depleted, the beneficiation of low-grade ...
IIron ore pelletisation (IOP) uses bentonite as a binding ron ore pelletisation (IOP) agent, and is added to dry iron ore to form pellets. Sodium bentonite is preferred for its excellent plasticity, dry bonding strength and high mechanical strength at high temperatures. Both sodium and calcium bentonite is used in ffoundry oundry
Binders. Innovative Alcotac organic binders are used in a wide variety of mineral-substrates to improve agglomeration processes. Organic binders help to reduce the level of impurities and emissions.

In order to pelletize iron ore fines and/or concentrate, a binder is needed. Binder selection can vary from process to process depending on the unique goals of the project at hand, but bentonite clay is a common choice. Various additives may also be included with the feedstock to
iron-making processes such as the blast furnace or the DR-plant. Hence, an agglomeration technique should be applied to fine concentrate. The most commonly employed one is pelletizing in iron ore industry. In pelletizing, iron ore, water and a binder are balled in
Anew kind of iron ore pellet binder named humic acid modifying bentonite (HA-MB) has been developed by the authors group, which has the advantages of both organic HA and inorganic bentonite. The green pellet strength can be obviously improved by using the HA-MB binder. In this study, the detection of the characterization of HA-MB was ...

a) Iron ore nes of 0-2 mm size can be briquetted directly. Due to the coarser sizes of iron ore nes, voids are created inside the briquettes the porosity becomes similar to pellets. b) The conversion cost of briquetting is Rs. 1,500 per ton, which is lower than pelletisation. c) Investment on the plant is also lower, i.e., 3.5 - 4 tons per ...
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.
Reduction plant or COREX. Pelletisation was invented to make use of Blue dust and ultra fine concentrate generated in the Iron ore beneficiation plants. Pellets have the benefit of lower gangue on account of beneficiated ore. ... China, Mill A 2009 China, Mill B 2009 Area (m 2) 450 495 450 Productivity (t/m 2/hr)
