Why do we extract copper from low grade ores?

2020-1-30  Accordingly, how do you extract copper from low grade ores? Leaching is the process to extract pure copper from a low grade ore. Leaching is the process of extracting substances from a solid by dissolving them in a liquid, in this process the ore is dissolved in liquid but not impurities. Then the copper solution is reacted with iron to get pure copper (reduction process).
