Advances in Alternative Binders for Iron Ore Pellets

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 2.4 MJ of additional energy during the production of one metric ton of pig iron.

Comparison between bentonite and serpentinite The binder more used to make pellets is bentonite, which is an item of significant cost in the process. The present paper aims at evaluating the use of serpentinite instead of bentonite. The results obtained show that the full substitution of bentonite for serpentinite is unfeasible. However a potential does exist for using serpentinite and bentonite together in the iron ore palletizing

Pelletizing - Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.

USA - Bentonite binder composition - Google PatentsA 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.Microstructure of Bentonite in Iron Ore Green Pellets Sodium-activated 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.

IMPROVEMENT OF MECHANICAL STRENGTH OF IRON ORE PELLETS 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

Binding mechanisms in wet iron ore green

Industrial iron ore green pellets are over-saturated and a supporting "network" of viscous liquid is formed on the green pellet surface. At least half, probably more, of the total binding force appeared to be due to the cohesive force of the network. The other half (or less) of the total compression strength can be explained by the capillary force. Due to irregularities on green pellet FLOFORM ™ Iron Ore PelletizationFLOFORM™ 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 bothBinding mechanisms in wet iron ore green pellets with a 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 [PDF] ALTERNATIVE BINDERS TO BENTONITE 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. Therefore, alternative binders to bentonite have been tested. Organic binders are the most studied binders and they yield pellets with good wet strength
