Extraction of Metals - Result Question 51
####51. Partial roasting of chalcopyrite produces
(a) $Cu _2 S$ and $FeO$
(b) $Cu _2 O$ and $FeO$
(c) $CuS$ and $Fe _2 O _3$
(d) $Cu _2 O$ and $Fe _2 O _3$
Show Answer
Solution:
- $2 CuFeS _2+O _2 \longrightarrow Cu _2 S+2 FeS+SO _2 \uparrow$
$2 Cu _2 S+3 O _2 \longrightarrow 2 Cu _2 O+2 SO _2 \uparrow$
$2 FeS+3 O _2 \longrightarrow 2 FeO+2 SO _2 \uparrow$
