CHXII06:GENERAL PRINCIPLES AND PROCESSES OF ISOLATION OF ELEMENTS
321033
Before introducing \(\mathrm{\mathrm{FeO}}\) in blast furnace, it is converted to \(\mathrm{\mathrm{Fe}_{2} \mathrm{O}_{3}}\) by roasting so that:
1 It may not be removed as slag with silica
2 It may not evaporate in the furnace
3 Presence of it may increase the m.p. of charge
4 None of the above
Explanation:
\(\mathrm{\mathrm{FeO}}\) can form slag with \(\mathrm{\mathrm{SiO}_{2}}\), \(\rm{\mathrm{SiO}_{2}+\mathrm{FeO} \longrightarrow \mathrm{FeSiO}_{3}}\)
