Effect of Limestone and Dolomite Flux on the Quality of Pellets
Request PDF Effect of Limestone and Dolomite Flux on the Quality of Pellets using High LOI Iron Ore Owing to the depletion of high-grade iron ore quality, 12.5.1.2 Iron Production Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the12.5 Iron And Steel Production US EPA

Iron Ore Pelletizing Process: An Overview IntechOpen
The iron ore pelletizing process consists of three main steps: Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives—anthracite, dolomite—and binders are prepared The three materials are mixed in the batching machine according to the required proportions, fed via a belt conveyor into a ball mill for grinding, and then pressed into pellets. The calcined dolomite is sorted first, and a jaw crusher is used to crush ferrosilicon from the raw material storage yard to a particle size of about 10–20 mm.Magnesium Smelting via the Pidgeon Process SpringerLink

Dolomite (mineral)
Dolomite and calcite look similar under a microscope, but thin sections can be etched and stained in order to identify the minerals. Photomicrograph of a thin section in cross and plane polarised light: the brighter mineral grains in the picture are dolomite, and the darker grains are calcite.. Dolomite (/ ˈ d ɒ l. ə ˌ m aɪ t, ˈ d oʊ. l ə-/) is an anhydrous carbonate mineral Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. Pellet plants sized from 1.2MTPA to 9MTPA. Engineering and design of complete plants from ore receiving to pellet discharge. Supply of the main pelletizing and induratingIron ore pelletizing TON

Characterization of Fluxed Iron Ore Pellets as Compared to Feed
The effect of lime addition in hematite iron ore pellets on its physico-chemical as well as mechanical properties with respect to blast furnace requirement was studied in a laboratory scale withSINTER COOLING1) The process involves Cooling of sinter inside circle cooler. 2) The sinter cake discharged from the hot sinter breaker, 120 ~ 0 mm, at temperature of 750 ~ 850 deg. C in average is charged into circular sinter cooler. 3) Product Sinter temperature should be reduced down to < 100deg.Sinter Plant Presentation (Sinter Operation) [PDF Document]

Evolution of Structure and Metallurgical Properties of Iron Ore Pellets
Properties of bentonite include: swelling capacity 16 times; swelling index 28.8 mL/2 g; effective viscosity 46.5 mPa s. Research factors: the basicity of the pellets B 2 = CaO/SiO 2 and MgO content (complete factorial experiment 2 2).The range of variation of factors: B 2 = 0.5–1.2 (corrected by the addition of limestone) and MgO = 0.5–1.8 dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO 3) 2]..
