- #19How is leaching carried out in case of low grade copper ores?
Ans : In case of low grade copper ores, leaching is carried out using acid or bacteria in the presence of air. In this process, copper goes into the solution as Cu2+ ions.
The resulting solution is treated with scrap iron or H2 to get metallic copper.
