General Principles and processes of Isolation of Elements
medium
કોપર ના નિષ્કર્ષણ માં $Cu_2O$ એ કોની સાથે મળીને ધાતુ બનાવે છે
A
$FeS$
B
$CO$
C
$Cu_2S$
D
$SO_2$
Solution
In the extraction of copper from its sulphide ore, the metal is formed by reduction of $Cu _2 O$ with $Cu _2 S$.
The sulphide ore of copper is heated in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide.
Self-reduction of $CuS$ to $Cu$ can be carried out in either Bessemer converter or Pierce-Smith converter.
$2 Cu _2 S +3 O _2 \rightarrow 2 Cu _2 O +2 SO _2$
$2 Cu _2 O + Cu _2 S \rightarrow 6 Cu + SO _2$
