અશુદ્ધ આયર્ન બનાવવા વાતભઠ્ઠીમાં નીચેની પ્રક્રિયાઓ થાય છે. તો સ્લેગની બનાવટની પ્રક્રિયા જણાવો. 

A

$Fe_2O_{3(s)} + 3CO_{(g)} \rightarrow 2Fe_{(l)} + 3CO_{2(g)}$

B

$CaCO_{3(s)} \rightarrow CaO_{(s)} + CO_{2(g)}$

C

$CaO_{(s)} + SiO_{2(s)} \rightarrow  CaSiO_{3(s)}$

D

$2C_{(s)} + O_{2(g)} \rightarrow  2CO_{(g)}$

(AIPMT-2011)

Solution

The fusible material formed by the reaction of flux and gangue.

$\mathrm{FeO}+\mathrm{SiO}_{2} \rightarrow \mathrm{FeSiO}_{3}$

$\mathrm{CaO}(\mathrm{s})+\mathrm{SiO}_{2}(\mathrm{s}) \rightarrow \mathrm{CaSiO}_{3}(\mathrm{s})$
