Question

write the process of extraction of Cu from its ore​

Answer 1

Answer:

Given below are the steps for extraction of copper from its ore. Write the reaction involved.

(a) Roasting of copper (I) sulphide.

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

(c) Electrolytic refining.

Answer 2

                                        i hope this help you

Answer:

(a) 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-
