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 CuSO, (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 CUSO̟ 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 punmber of sta ges reauuired
