Iron Ore Pelletizing Bentonite

Bentonite is commonly used in pelleting of iron ore. The use of bentonite as binding agent is quite common in the world due to its availability and its being cheap. Montmorillonite montmorillonite (Al, Mg)2 (OH)2 (Si, Al)4 O10 n. H2O, which the main mineral of bentonite, is fine grained. Specific surface area reaches up to 10.000 cm2/gr.

Jan 01, 2006 Calcium bentonite has a higher green strength, lower dry strength, lower hot strength, and better flowability than sodium bentonite. Methods of testing sand–clay mixtures are outlined in publications of the American Foundrymen's Society (Anonymous, 1963). 3. Pelletizing iron ore. Sodium bentonite is used to pelletize iron ore (Devaney, 1956).

is because imported lumpy iron ore has reduced demand for IOP-grade bentonite as a binder for Chinese iron ore fines such as magnetite. The CNMIA reported recently that Chinese IOP production was approximately 130m tonnes, consuming some 2.5m tpa of bentonite at an addition rate of about 2% bentonite per tonne of iron ore.

IMPROVEMENT OF MECHANICAL STRENGTH OF IRON ORE

this study is to investigate the use of sodium, calcium, and mixed type of bentonite samples as a binder in the pelletizing of fine iron ore concentrate. Experimental Materials Magnetite and bentonite samples Magnetite concentrate (Fe 3 O 4) used in the studies was obtained from the Divrigi Iron Ore Concentration & Pelletizing Plant (Turkey).

Effect of Bentonite on the Pelleting Properties of Iron

The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.

Calcium bentonites used in pelletizing are generally activated by soda. In the crude fall test, the raw pellet is repeated until a pellet is dropped down from a 45 cm height onto steel surface until it is broken. When sodium bentonite is used as binder, the strength of the pellets is measured 9-10 drops / 45 cm, while this value is 4-5 drops

Bentonite Everything about Bentonite!

Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite.
