introduction toiron orepellets andpelletizingprocesses

The various advantages ofiron orepellets are given below.Iron orepellet is a kind of agglomeratedfineswhich has better tumbling index when compared with theiron oreand it can be used as a substitute for theiron orelumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %)

DRI, also known assponge iron, is the product of reducingironoxide in the form ofiron oreand steel plant wastes into metalliciron, below the melting point ofironand typically in the range of 800–1200 °C.Ironoxide is charged into shaft furnace, rotarykiln, or fluidized beds in the form of pellet,iron orelumps, orfines. The reduction takes place using gaseous reductants (CO + H

JCL producesiron orepellets fromiron ore finesusing grate-kiln technology. Thistechnologyallows production of superior grade feed material for DRI and blast furnace operations. Once thefinesare wet ground, they are dewatered, and the resulting concentrate is then mixed with binder and other additives to produce pelletiser feedstock

Jan 05, 2012· D. Zhu, inIron Ore, 2015. 16.3.1.1 Background. In a DR process,iron orepellets and/or lumpironores are reduced by a reducing gas to produce DRI or hot briquettediron(HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based
