Minerals | Free FullText | Induration Process of MgO Flux ...
Magnetite iron ore, Bentonite and lightburned magnesia contained in the pelletizing materials were used for the Fe source, the binding media, and adjusting MgO content in pellet, respectively. Actually, the lightburned magnesia is an MgO bearing flux prepared by an elementary roasting with magnesite.
FLOFORM ™ Iron Ore Pelletization SNF Holding Co.
3 FLOFORM™ Iron Ore Pelletization. Use of FLOFORM™. Pelletization is a tumble/growth agglomeration mechanism for solid particulates, which must comply with several key points from the strength of the liquid bond during the seeding, the control of the water migration during the balling to the solid bonds resistance during the indurating stage.

How does iron ore form? Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite (Fe2O3) or magnetite (Fe3O4). About 98% of world iron ore production is used to make iron in the form of steel. Nearly all of Earth's major iron ore deposits are in rocks that formed over billion years ago.

Pellet (Iron ore) Mining Fundamentals
Iron ore pellets are marblesized balls of iron ore that are fused with clay for transportation, and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from a lowgrade iron ore involves processes like mining, crushing, separating, concentrating, mixing, pelletizing, and shipping.
USA Pelletizing process Google Patents
It has been found that for satisfactory pelletizing of most iron ores by use of this process, that the total heat required is about 800,000 B. t. u. per ton of ore for hematite in a shaft furnace, and that about 30,000 cubic feet of air are required to cool the compacts in the cooling zone and provide oxygen necessary for combustion of the combustible constituents in the burning zone of the process.
