Iron Ore Pelletizing Process: An Overview | IntechOpen
The presence of liquid or semiliquid phases is more pronounced in fluxed pellets where acid constituents normally from the ore (, SiO 2 and Al 2 O 3) may react with basic ones added in the form of fluxes (, CaO and MgO). This reaction may result in the formation of a slag phase.
Fluxed synonyms, fluxed antonyms
Conversion to fluxed pellets at Inland Steel was driven by many benefits in the blast furnace (BF), and basic oxygen furnace (BOF), shops at the Indiana Harbor Works. Because the BF operation is more stable with fluxed pellets, the silica level also becomes less variable.

Fluxed | definition of fluxed by Medical dictionary
The offline XRF unit, previously used for the fluxing control, is now used for routine analysis of filter cake, pellets, and fluxstone, and backup analysis of fluxed concentrate. During 1987 and 1988, Minorca made a lowsilica, fluxed pellet with an organic binder, lowering the silica content to 4.
