Question

Describe the extraction and refining of copper from its ore

Answer 1

hi mate

here is your answer

Cu is generally extracted from Cu2S ore.

or

It can be obtained by electrolytic refining of molten copper salt.

We will here show extraction of Cu from its sulphide ore.

Now,

Copper ore = Cu2S

Since its sulphide ore ,we will do roasting.

2Cu2S + 302-------roasting------->

2CU20 + 2So2

Now we will treat the roasted ore(Cu20) with unroasted ore(Cu2S) which will get auto reduction.

So,

2Cu2O + Cu2S -------auto reduction------>

6Cu + So2

So we got Cu from its sulphide ore by two process --->

1) Roasting of sulphide ore of Cu

2)Auto reduction of Cu when the roasted

ore(Cu20) is treated with unroasted ore(Cu2S).

hope it helps
