member), though the values were ten to thirty times lower than in the case
of CS. h e inl uence of i ring temperature was also statistically signii cant,
but much less than in CS [3].
Unlike the CS and WA , most of the output parameters presented in
tableĀ  4.3 were at higher impact of other major oxides contents, and not
as much by i ring temperature. h e highest inl uence can be seen in FS
in the case of Al 2 O 3 xFe 2 O 3 and Fe 2 O 3 xTiO 2 terms. h e next signii cant
inl uence on FS showed Al 2 O 3 and TiO 2 linear terms. h us, FS is to be the
most af ected by biotite and chlorite content, but also hematite/rutile pres-
ence. Kaolinite and smectite were present in most of the samples, although
to a low quantity. h eir signii cant inl uence is rel ected in SiO 2 xAl 2 O 3
term. Calcite signii cantly reduces FS , especially when present in the
form of large concretions [2]. CaO inl uence in the case of FS , according
to ANOVA, was the most pronounced in interchange parameters Al 2 O 3
x CaO, SiO 2 x CaO and CaO x MgO, and thus showed the dependance
of FS on anorthite, montmorillonite, and dolomite contents. Calcite can
react with quartz, or Al 2 O 3 and SiO 2 from clay mineral dehydroxylation
