Cu extracting reagent 1. High efficiency 2. Excellent stability 3. Excellent selectivity of copper and iron
Copper extracting reagent
Advantage:
1. DZ988 may be used alone, also can with arbitrary proportion and Lix984. Lix973. N902 etc. extractant mixed using.
2. Practice has proved that: DZ988 saturation capacity in the extraction of copper is more than Lix984. extraction kinetics, phase indicators and Lix984 considerable time. The price of DZ988 is lower than the Lix984.
3. DZ988 consumption when the extraction of added modifier than the extraction agent 30% less consumption. Add a modifier of the extraction solvent, extraction systems are susceptible to dirt, as modifier above functional groups easily with liquid hydrogen in the formation of solid particles.
4. As DZ988 has excellent stability, phase speed, excellent selectivity of copper and iron, even if the feed solution containing Fe to 2g / L, still can make the Cu / Fe separation factor greater than 2000.
