Worldwide demand of copper is consistently increased, so the mineral reserve nation controls over the export of raw ore. Besides, decreasing of grade of copper ore is one of big problems. Hydro-metallurgical process has been developed to treat low grade copper ore. However, it is still difficult to separate copper from iron in process.
In this study, we tried to recover copper separately from iron in leaching solution by solvent extraction method. Extraction is carried out by using LIX984N as extractant and artificial leaching solution which contains 18g/L copper and 17g/L iron. At first, pH range that copper separate from iron is verified through pH isotherm experiment. And then, we carried out extraction experiment with dilution rate of leaching solution, pH and the concentration of LIX984N and so on. As a result, copper is extracted 99% from 3 stage counter-current extraction experiment. In this case, iron is extracted only 0.1%.
