A treated ore containing inert solid gangue and copper sulfate is to be leached in a countercurrent multistage extractor using pure water to leach the CuSO4 . The solid charge rate per hour consists of 10000 kg of inert gangue (B), 1200 kg of CuSO4 (solute A), and 400 kg of water (C). The exit wash solution is to contain 92 wt % water and 8 wt % CuSO4 . A total of 95% of the CuSO4 in the inlet ore is to be recovered. The underflow is constant at N = 0.5 kg inert gangue solid/kg aqueous solution. Calculate the number of stages required.
