Advances in Alternative Binders for Iron Ore Pellets ADS NASA/ADS

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 MJ of additional energy during the production of one metric ton of pig iron Bentonite replacement requires an in

Iron Ore Pelletization Part II Inorganic Binders

Bentonite clay has traditionally been used as a binder to make iron ore concentrate pellets but it is expensive and contaminates the pellets A general view of Brazilian types of iron ores

Microstructure of Bentonite in Iron Ore Green Pellets

The microstructure of bentonite in magnetite pellets is revealed for the first time using scanning electron microscopy and it is shown that clay tactoids were very well dispersed and formed a voluminous network occupying the space available between mineral particles Abstract Sodium activated calcium bentonite is used as a binder in iron ore pellets and is

Iron Ore Pelletizing Process An Overview IntechOpen

Bentonite an inorganic binder has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s Bentonite promotes the formation of ceramic bridges between particles which can minimize the number of pellets that collapse during firing

Utilization of Kimberlite as Binder for Iron Ore Pellet Making

Overall the binder formulation made of Kimberlite and Lime in 50 50 ratio performed well as binder for iron ore pellet making and its performance was comparable with conventional binder Bentonite The performance of the iron ore pellet produced with Kimberlite binder formulation under blast furnace condition were better than the conventional

Binding Mechanism in Green Iron Ore Pellets with an Organic Binder

Zhang et al [22] compared the adsorption characteristics of humic acid on montmorillonite guided the preparation of a novel iron ore pellet composite binder and determined that the composite

A review of binders in iron ore pelletization Semantic Scholar

The majority of iron ores must be ground to a fine particle size to allow the iron oxides they contain to be concentrated and the concentrate must then be agglomerated back into large enough particles that they can be processed in blast furnaces The most common agglomeration technique is pelletization which requires the use of binders to hold the iron

Design of saccharide based organic binder for low grade iron ore

One problem encountered while using bentonite binder was the generation of iron ore slimes with comparatively high silica and Common organic binders that have been studied for iron ore pellet formation are Carboxy methyl cellulose CMC humic substances View PDF View article CrossRef View in Scopus Google Scholar [8] V Jain V
