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 0.01-0.05% prior to balling, i.e. about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
Jun 10, 2011· 1. Introduction. Bentonite is the conventional binder in iron ore pelletization and used at 0.5–1.5% addition levels in the pellet feed by weight of iron ore,, .It controls the moisture of iron ore concentrate in the pellet feed and improves physical properties of .
A few researchers have investigated the use of boron compounds in iron ore agglomeration and found promising results which have been covered in this paper. Keywords: Iron ore, Pelletization, Agglomeration, Bentonite, Organic binders, Boron compounds, Colemanite. 1.
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.
Organic binders have been used as an attractive alternative to bentonite in iron ore pelletizing process, mainly because it burns without leaving any residue in the final pellet. There are two main types of organic binders, those based on cellulose compounds and other based on polyacrylamide polymers.
alternative binders to bentonite for iron ore pelletizing: part i: effects on physical and mechanical properties 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 ...
Since the purpose of iron ore processing is to remove silicate minerals from the ore, adding silicates back in the form of binder is counterproductive. This has prompted long-term interest in developing or discovering binders that contain no silica. Therefore alternative binders to bentonite .
ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE PELLETIZING: PART I: EFFECTS ON PHYSICAL AND MECHANICAL PROPERTIES. ... There is great incentive to reduce bentonite use in iron ore pelletization by ...
BASF NOVEL IRON ORE BINDER TECHNOLOGY: STUDY OF BENTONITE MODIFICATION* Adrian Villanueva1 Shane Hoff2 Alexej Michailovski3 Abstract In this study, we compare the influence of two water soluble polymer-based organic binders added to bentonite, to form a hybrid-binder system for Iron Ore Pelletization.
ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE . The exploitation of medium and low grade iron ores is possible after enrichment. Low grade iron ores such as magnetite and hematite with impurity gangue minerals containing e.g. Si, Al, Ca, Mg, Na, K, P and S compounds have to be upgraded to an acceptable sufficient level of iron grade.

Bentonite adds unwanted silica to the final concentrated iron ore product. Excess silica from bentonite addition has been calculated to consume approximately 2.4 MJ of additional energy during the production of one metric ton of pig iron. Bentonite replacement requires an in-depth understanding of how alternative binders affect the ...
Nov 14, 2011· Kemira has developed a series of KemPel™ synthetic organic binders for iron-ore pelletization. The technical and commercial benefits of this technology were presented in August to the Advanced Sustainable Iron & Steel Making Center (ASISC) conference at Michigan Technological University in Houghton, Michigan.
during pre-heating, contrary to bentonite clays commonly used in pelletizing iron ore for blast furnaces. Due to the need to process increasing volumes of low grade iron, interest in organic binders has increased lately. Organic binders tend to produce good quality wet pellets which however often lack in compressive strengths after sintering.
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.
