Grade of iron ore is usually determined by the total ...
Why is scrap iron copper economical? – Restaurantnorman.com
Why is scrap iron copper economical? Scrap iron is used to displace copper because it is a more reactive, cheaper metal, making it a cost-effective way to produce copper. This causes the iron ion to displace the copper to form iron sulphate, with solid copper being produced as a result.
