Investigation of Copper Recovery rate from Copper Oxide

2019-1-1  The study which varied different concentrations of sulfuric acid liviviant obtained the maximum copper recovery at 1 M from which the leaching yielded 29.89 g/L copper. The increase in copper recovery was observed as sulfuric acid concentration was varied from 0.25 M to 1 M and copper recovery began to decrease from 2 M to 3M.
