| Abstract: | Enriching copper from biological leaching solution after removal of Fe by NF membrane technology is studied. The in-fluences of operating pressure and temperature on permeate flux, the copper rejection and the conductivity of permeate are investigated. Operating pressure 15bar, temperature 30℃, flux 14 L/min, concentrates 3.7 times are optimal conditions during the experiment. Un-mer this condition, the copper rejection is over 93.1% , the concentration of Cu in concentrated solution is 0. 764 g · L^-1. |
