Roasted copper ore containing CuSO4 is to be extracted in a counter stage extractor. A feed consisting of 250 kg gangue, 50 kg CuSO4 and 25 kg water is charged in the extractor. The strong solution produced consist of 85% H2O and 15% CuSO4 by mass. The recovery of CuSO4 is 90% of that in the ore. Pure water is to be used as a fresh solvent. After each stage, 1 kg of gangue retained 4 kg of solution. If equilibrium is attained in each stage, solve for the following: 6. Weight of solution that leaves the first stage A. 25 kg B. 255 kg C. 300 kg D. 1000 kg 7. Percentage of CuSO4 in the final discharge is A. 0.2% B. 0.3% C. 0.4% D. 0.5% 8. The number of stages required is close to A. 7 B. 8 C. 9 D. 10
