At a site, low grade copper ores are available and zinc and iron scrap – InterviewSolution

1.	At a site, low grade copper ores are available and zinc and iron scraps are also available. Which of the two scraps would be more suitable for reducing the leached copper ore and why?
Answer» Solution :Zinc being above IRON in the electrochemical series (more REACTIVE metal is zinc), the reduction will be FASTER in case zinc SCRAPS are used. But zinc is costlier metal than iron so using iron scraps will be advisable and advantageous.
