Heap Leaching Time. If the ore grade is high (.7 to 1.2% T, Cu) the early solution off the pad will be 30 g/l copper or higher. In 6 meter and 15 meter column tests early OFF solutions have been as high as 70 g/l copper. c. There is no decisive break, between the Dissolution period and the Pore Diffusion period.
