The replacement of bentonite as the standard iron ore binder is an important factor in the future of iron processing. Bentonite adds 0.7%-1.0% unwanted silica to the final iron product.
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …

Cement. Cement is used as a binder for briquetting coal, char, and charcoal and then for briquetting iron and steel wastes.Now cement is widely used in the steel plant as one of the main binders. But use cement will bring gangue and crystal water, so to reduce the cement cost can help to increase the purity of briquette, as cement need a long time to …
4. Briquetting with a Binder Cold bond briquetting may offer a method for recycling the res-idues. Fines, dusts, and sludge can be briquetted using a binder to a form that is suitable for charging into the Midrex shaft. To get briquettes with sufficient mechanical strength and thermal stability, a binder is needed. With the selection of a binder,
Blending (Optional): Mill scale fines, another steel byproduct high in iron content, can be blended with the dewatered sludge to increase the briquette's density and iron content. 3.
Main advantages of iron ore briquettes. Briquettes emit less carbon dioxide than traditional agglomeration processes (pelletizing and sintering). It can reduce CO2 emissions in the …
The recycling of steel plant side streams through cold-bonded briquettes has become quite common. However, Portland cement is mainly used as a binder in the briquettes, contributing significantly to the energy consumption, costs, and carbon footprint associated with the production of cold-bonded briquettes. This paper reports on a more …
What are iron ore pellets? Iron ore pellets are spheres of typically 8-16 mm to be used as feedstock for blast furnaces. They contain 64-72% iron and additional materials, which can adjust the chemical composition and metallurgical properties of the pellets. The iron ore pelletization is the process of converting iron fines less than 200 …

Clay iron ore fines, blast dust, and cinder were also briquetted without binders, plasticizing the mixture by grinding the components and moistening. ... The successes in the briquetting of iron ore fines and anthropogenic materials achieved at the very beginning of the twentieth century and the dominance of briquetting as the only …
GoodRich offers high-pressure briquetting plant from a specialized manufacturer in China, to briquette iron ore fines. These briquettes can be used in the rotary kilns for making sponge iron. Briquetting is an …
It was the earliest fine iron-bearing material agglomeration process in the steel industry. Briquetting process started in the 1830s. In the late nineteenth century, it was introduced in steel making industry and used for iron ore powder agglomeration. Due to low productivity of single machine, this process is not used very often in steel ...
The key factors that lead into an effective organic binder are good dispersion into the iron ore, the ability to maintain the dispersion of the iron ore during the binding process, and limited water retention. The factors leading into a useful organic binder are more complex, depending on the availability of the material locally and the ...
