Can fly-ash extend bentonite binder for iron ore

01/12/2000 Bentonite is currently the most common binder used during iron ore agglomeration This fly-ash did not meet classification criteria to be characterized as either Class F or Class C, according to the ASTM standard (ASTM C618-98, 1998) shown in Table 2,

Can fly-ash extend bentonite binder for iron ore

There is great incentive to reduce bentonite use in iron ore pelletization by improving its effectiveness. In order to make bentonite more effective, it is necessary to understand the actual binding mechanisms so that they can be properly taken advantage of. Bentonite use could also be reduced by replacing bentonite with even lower-cost binders, such as high-carbon fly-ash based binder (FBB). While FBBs can be used alone as binders,

Understanding the bonding mechanisms in iron ore pellet

In this paper, experiments are described where bentonite was mixed with various ratios of cornstarch and fly-ash, and pellets were agglomerated using 0.66 % w/w binder. Ca(OH)2 and CaCl2 were

Use of Boron Compounds as Binders in Iron Ore Pelletization

researchers have investigated the use of boron compounds in iron ore agglomeration and found promising results which have been covered in this paper. Keywords: Iron ore, Pelletization,Agglomeration, Bentonite, Organic binders, Boron compounds, Colemanite. 1. IRON ORE PELLETIZING The main raw material in iron-steel industry is iron ore. Iron ores can be classified as

Choosing A Binder in the Agglomeration Process

The same holds true for a cement binder; the cement may work well during the agglomeration process and achieve desired strength characteristics, but would not break down, and would leave cement in soil. Molasses, starches, and other organic binders, however, not only function well as binders for fertilizer products, but also break down quickly. They can even add micro-nutrients to the soil.

Iron Ore Agglomeration Technologies IntechOpen

18/05/2017 Five iron ore agglomeration technologies can be defined: briquetting, nodulization, extrusion, pelletization and sintering. Sintering and pelletization are the most important agglomeration technologies, in this way, in the EU-27, 14 countries operate 34 iron ore sinter plants with 63 iron ore sinter strands, producing in the first decade of the twenty-first century 130 million tons of sinter

Organic binders for iron ore pelletization and

Historically, bentonite has been used in the agglomeration process in North American iron ore plants. In 1986, Eveleth Mines replaced bentonite with Peridur, a carboxy methyl cellulose organic binder used in conjunction with 1% limestone. Since May of 1993, Allied Colloids` Alcotac FE8 has been used by Eveleth as the replacement for bentonite. This paper discusses the performance benefits

Effect of molasses binder on the physical and mechanical

Abstract: Molasses was used as an alternative binder to the bentonite binder. The change in moisture absorption by pellets prepared with different iron ores and different molasses contents were investigated. Iron ore properties exerted the major effect on pellet behavior and final pellet quality. The absorbed moisture content of pellets prepared without binder, bentonite-added pellets, and
