ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE

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 have been tested for many years. Because of good binding properties without contaminating the product

Pelletization of iron ore fines with parameter

Bentonite is the most commonly used binder in iron ore Pelletization. It not only controls the moisture in iron concentrate but also remarkably improves physical properties of the pellets. However, there are some major drawbacks with the use of betonies. The most striking is the contamination of the product with gangue (silica). Addition of 1% betonies to an iron ore concentrate results in a

Effectiveness of Organic Binders for Iron Ore Pelletization

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 blast furnace feed material. Approximately 15 pct of the

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.

melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into product pellets. The pellets
