Effect of adding limestone on the metallurgical properties

10/08/2015· In the fluxed pellets studied here, limestone has decomposed (see Fig. 2b) and CaO has taken gaseous sulphur into a solid solution of CaO–CaS, ending up with a higher S content in the fluxed pellets compared to the non-fluxed ones. This was verified with FESEM-EDS analyses showing 29–31 wt.% Ca, 23–37 wt.% O, 24–26 wt.% S and max 1 wt.% Fe in the decomposed carbonate grains.

Effect of limestone and dolomite flux on the quality of

The physical and metallurgical properties, i.e., CCS, porosity, SI, RDI, and RI of the fluxed pellets were optimized. At particular ratio of limestone and dolomite, synergistic effect was observed with respect to pellet characteristics.

Effect of limestone and dolomite flux on the quality of

23/10/2020· The effect of flux (dolomite and limestone) was studied in the pelletization process using the feed materials, i.e., goethetic-hematite iron ore fines and anthracite coal. The experiments were carried out using individual flux or different combination of fluxes.

Fluxed Iron Ore Pellets. The moisture content of iron ore fluxed pellets was calculated proportionally according to the amount of water required by pure iron ore and pure limestone pellets 135 and 165 respectively therefore a fluxed charge containing 10 limestone needs 138 water and a charge containing 20 limestone needs 141 water content.

Development on Iron Ore Pelletization Using Calcined Lime

It is found that calcined lime fluxed pellet without bentonite and limestone shows very good dry compressive strength (3.5 kg/pellet) and improved green compressive strength (1.5 kg/pellet), drop numbers (12 Nos), cold crushing strength (310 kg/pellet) and reduction properties.

In limestone-fluxed pellets with bentonite as a binder although formation of calcium ferrite was noted at the basicity of 0.8 its formation in appreciable quantities was delayed until the basicity of 1.6. For the pellets produced with a combination of dolomite and limestone even at the basicity of 1.6 only minor amounts of this phase were . Get Price; limestone fluxed

Influence of flux additives on iron ore oxidized pellets

05/08/2010· Six additives, i.e., limestone, lime, magnesite, magnesia, dolomite and light-burned-dolomite, were added for investigating their influences on the pellet quality. For green balls, adding lime and light-burned-dolomite makes the wet drop strength decrease firstly, and then increase with further increase of additive dosage. Ca(OH)2 affects the bentonite properties at the beginning, but the

Cleveland-Cliffs Inc. Commercial and Products Iron Ore

Standard pellets require less processing, are generally the least costly pellets to produce and are called “standard” because no ground fluxstone, such as limestone or dolomite, is added to the iron ore concentrate before turning the concentrate into pellets. In the case of fluxed pellets, fluxstone is added to the concentrate, which produces pellets that can perform at higher productivity

Reducibility Of Cobblestone And Limestone Rate In Blast

It shows that with a higher portion of non-fluxed pellets (up to 60%) in the charged burden it is necessary to charge limestone in the furnace to achieve the required basicity of blast-furnace slag. What is the purpose of limestone in a blast furnace? Quora. Limestone is the reducing agent,without limestone the iron ore i.e Fe2O3 will never get reduced to Pig iron i.e Fe .. “calcination

BEHAVIOUR OF COATINGS ON OLIVINE FLUXED PELLETS IN

Different coatings on olivine fluxed blast furnace pellets were examined in LKAB’s experimental blast furnace, Luleå. The aim of coating is to decrease dust generation, prevent sticking and to bind alkali for smoother operation. The coating materials were kaolinite, bauxite, olivine and limestone. Uncoated pellets were studied for reference. Probed samples from upper and lower shaft were
