Question

how is leaching carried out in case of low grade copper ores?

Answer 1

Heya!

Its very simple friend.

Here is your answer.
------------------------------------------------------------------------------------------------------
See ,For low grade copper ores, leaching is carried out with acid or bacteria in the presence of air.

So,During this process, copper goes into the solution as Cu2+ ions.

And,The solution is then reacted with scrap iron or H2 to get metallic copper.
