1/5/2019· Molasses was used as an alternative binder to the bentonite binder. The change in moisture absorption by pellets prepared with different iron ores and different molasses contents were investigated. Iron ore properties exerted the major effect on pellet behavior and final pellet quality. The absorbed moisture content of pellets prepared without binder, bentoniteadded pellets, and
Iron ore, water and a binder are balled in a mechanical disc or drum to produce wet pellets. bentonite is the most widely used binder in iron ore pelletizing industry. the use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of its acid constituents (sio 2
The replacement of bentonite as the standard iron ore binder is an important factor in the future of iron processing. Bentonite adds unwanted silica to the final concentrated iron ore product. Excess silica from bentonite addition has been calculated to consume approximately MJ of additional energy during the production of one metric ton of pig iron.
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
· Organic binders have been used as alternative to bentonite in the iron ore pelletizing process mainly because it burns without leaving residue in the pellet. There are two main types of organic binders, those based on cellulose and those based on polyacrylamide structures. The purpose of this investigation was to explore how an organic binder based on carboxymethyl cellulose structure
offers 1,474 bentonite in pellets products. About 8% of these are Bentonite, 0% are Other NonMetallic Minerals Products. A wide variety of bentonite in pellets options are available to you, such as classification, grade standard, and usage.
Floform Iron Ore Pelletiation. FLOFORM Iron Ore Pelletiation 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 120th of Bentonite. Depending on the quality of iron ore a dual binder
A bentonite binder composition and method of preparation is disclosed. The binder composition is particularly useful for pelletizing iron ore fines. It is prepared by intimately combining and mixing wet bentonite in a stockpile with soda ash, the moisture in the wet bentonite bringing about reaction to form an improved binder after a suitable aging period.
The use of conventional bentonite binder is favorable in terms of mechanical and metallurgical pellet properties, however, because of its acid constituents bentonite is considered as impurity especially for iron ores with high acidic content.

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. KEYWORDS: iron ore pelletizing, bentonite organic binder, boron compounds, colemanite, chemical and metallurgical properties.

the iron ore industry, methods need to be developed for producing domestic iron ore pellets that are economical and have superior metallurgical properties that will result in coke reduction during blast furnace smelting. Since iron ore concentrates consist of finely divided particles, they must be pelletized (with a binder) for use as
5/22/2013· Iron ore pellets are one type of ironrich, intermediate product used during primary iron and steel bonding at this stage depends on which binder is used. Bentonite is a low melting temperature silicate (Grim, 1978). Many factors are considered when choosing a particular binder for iron ore agglomeration. For example, with bentonite, it
The binding of iron oxide grains by bentonite clay to form pellets is a complex process, with a large number of variables, many of which have never been adequately studied. Current practice for pelletizing iron ore concentrates was developed in 1950''s during which bentonite clay was practiced as a binder and since then it has remained
11/13/2006· The beneficial influence of viscous binders in iron ore balling is well known from everyday practical operations. The large variety of binders studied in the iron ore industry was recently reviewed by Eisele and Kawatra . The most common binder is bentonite, of
The feasibility of producing direct reduced iron from coldbonded, selfreducing composite pellets, constituted from beneficiated iron ore slime, coke, and different binders (dextrin, bentonite

Higher Cation exchange capacities increasses binds Iron Ore particles very tightly. Requires minimum addition of Sodium Bentonite clay as binder, resulting minimal impurities in Pellets. Our Product gives High Productivity, Low Production Cost and High quality of Pellets. Price Range: Rs. 1000
Sodiumactivated calcium bentonite is used as a binder in iron ore pellets and is known to increase strength of both wet and dry iron ore green pellets. In this article, the microstructure of bentonite in magnetite pellets is revealed for the first time using scanning electron microscopy.
The results of these analyses showed that pyrite ash can be agglomerated to pellets and used in the iron production industry as a blast furnace feed. The crushing strength of the pellets containing calcium hydroxide and calcium chloride in addition to bentonite was better than the strength of pellets prepared using only bentonite binder.
