Abstract: In this study, sodium, calcium, and mixed bentonite samples were used as binders in the pelletizing fine iron ore concentrate obtained from the Divrigi Iron Ore Concentration Plant in Turkey. In the pelletizing tests, sodium bentonite sample was used as received and after upgrading process.

Comparative Analysis on stone Composition of Bentonite ...

composition affects the properties of bentonite. On the other hand, the measured physical characteristics are frequently used to interpret the mineralogical composition of bentonite. Two types of bentonite exist: swelling bentonite which is also called sodium bentonite and non-swelling bentonite or calcium bentonite.

Review of Organic Binders for Iron Ore Agglomeration

Many factors are considered when choosing a particular binder for iron ore agglomeration. For example, with bentonite, it is well known that using a western, or Wyoming, bentonite with high sodium to calcium ratio results in good pellets across a wide range of conditions (Nikol and Adamiak, 1973).

Iron Ore Pelletizing Bentonite - Karben Group

• The pressure resistance of pellets formed by activated calcium bentonite addition is much lower than the pellets formed with Karben Sodium Bentonite. • Also, when Activated Calcium Bentonite is used as a binder alone, the wet pellet efficiency is also reduced. • Karben Pellet Bentonite is specially prepared for Iron Ore Pelletizing.

Bentonite | Minerals & Mines | Gujarat Mineral Development ...

Owing to high green strength resulting from its property to absorb and then release moisture, bentonite is used in iron ore pelletisation. Sodium-based bentonite of 75 mm size finds suitability in iron ore pelletisation for bonding by user industries. Bentonite has also remarkable colloidal and …

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.

Effects of calcium hydroxide and calcium chloride addition ...

Oct 01, 2006 · The results of these analyses showed that pyrite ash can be agglomerated to pellets and used in the iron production industry as a blast furnace feed. The crushing strength of the pellets containing calcium hydroxide and calcium chloride in addition to bentonite was better than the strength of pellets prepared using only bentonite binder.

bentonite minerals ore -

Pelletizing Bentonite is used as a binding agent in the production of iron ore pellets. Through this process, iron ore fines are converted into spherical pellets, suitable as feed material in blast furnaces for pig iron production, or in the production of direct reduction iron (DRI).

Bentonite Clay | Opta Minerals

Bentonite is referred to as the “The Clay of 1000 uses” Foundries, Well drillers, Iron ore manufacturers and producers of kitty litter are the main consumers of Bentonite. Foundries use Bentonite when pouring metal cast molds. The clay withstands higher temperatures and the excessive heat will not cause the clay to lose its stone structure.

Iron Ore Pelletizing Bentonite | Karben Bentonite

Bentonite is commonly used in pelletting of iron ore. Bentonite plays an important role in using degradable iron ores with low grades upon pelleting. While activated calcium bentonites swell about 5-6 times of their volume, Sodium bentonites can swell up to 25-30 times.
