Question

write the correct process of extraction of copper from its ore ....
with proper steps​

Answer 1

Roasting of sulphide ore:

2Cu2S(s)+3O2(s) →2Cu2O(s)+2SO2(g)

(b) Reduction of copper (I) oxide with copper (I) sulphide:

2Cu2O+Cu2S→6Cu(s)+SO2(g)

This reaction is known as auto -reduction.

(c)Reaction for electrolytic refining:

At anode : Cu2+(aq)+2e-→Cu(s)

At cathode : Cu(s) →Cu2+(aq)+2e-

Answer 2

Answer:

Explanation:

Extraction of copper is done as follows...

one of ores from which copper is extracted is Cu2S.

The extaraction of copper from above that is copper glance occurs in 2 processes..

copper glance or copper sulphide ore is roasted in air when copper sulphide is oxidized to copper oxide.

2Cu2S+3O2=2Cu2O+2SO2

afer conversion , it is oxidized to obtain copper metal and sulphur dioxide.

2Cu2O+Cu2S=6Cu+SO2

this was ur exact answer..

Hp it hlps uhhh

Pls pls pls mark as the brainliest....
