Standard pellets generally require less processing, are normally the least costly pellets to produce and are called "standard" because no ground fluxstone (i.e., limestone, dolomite, etc.) is added to the iron ore concentrate before turning the concentrates into pellets. In the case of fluxed pellets, a fluxstone is added to the concentrate ...Get Price

Jan 10, 2014 · In the pyroxenite fluxed pellets, to adjust the MgO content of pellets from 0 to 3.0%, the amount of pyroxenite was varied from 0 to 10% in the green pellets. In the magnesite fluxed pellets, to adjust the MgO content of pellets from 0.5 to 3.0%, magnesite addition was varied from 1 to 7% in the green pellets.[PDF]Get Price
Fluxed pellets containing 10% and 20% limestone were produced in a laboratory balling drum. It was found that the pelletization kinetics were sensitive to the water content of the 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 ...

Examples of blast furnace behaviour with pellets of different high temperature behaviours will be shown. Work in full scale furnaces in the early and mid-1990's with experimental high iron content fluxed pellets, followed by experiments in the experimental blast furnace, has identified critical factors for LKAB pellet .[PDF]Get Price
of this paragraph, "fluxed pellets" are pellets produced in a process in which limestone, dolomite, olivine, or other basic flux additives are combined with merchantable iron ore concentrate. No subtraction from the weight of the pellets shall be allowed for binders, mineral and chemical additives other than basic flux additives, or moisture.Get Price
