General Principles and processes of Isolation of Elements
easy
કોપર પાયરાઇટ્સ માથી તાંબાના નિષ્કર્ષણ દરમિયાન આયર્ન........ તરીકે દૂર થાય છે ?
A
$FeSO_4$
B
$FeSiO_3$
C
$Fe_3O_4$
D
$Fe_2O_3$
Solution
The copper (II) ions in the copper pyrite are reduced to copper (I) sulphide (which is reduced further to copper metal in the final stage).
The iron in the copper pyrite ends up converted into an iron (II) silicate slag which is removed.
$\mathrm{CuF} \mathrm{eS}_{2}+\mathrm{SiO}_{2}+4 \mathrm{O}_{2} \rightarrow \mathrm{Cu}_{2} \mathrm{S}+2 \mathrm{FeSiO}_{3}+3 \mathrm{SO}_{2}$
