Today, metals recovery from solid waste is an important area that it has been researched around the world. Constant extraction of non-renewables resources such as metals has occasioned an available materials declining, for example the metals content in ores has been decreased over the years. The mining solid waste has becoming a potential resource for metal supply. The aim of this work is the study of metal separation, such iron and nickel from sulfuric liquor obtained in leaching process of mining waste using solvent extraction. In this work, it will be assessed different parameters to separate the interest metals. Initially, it will be chosen the system that obtains the higher extraction of iron. Then, the aqueous phase will be used to develop test in order to recover nickel. The results obtained will be evaluated by the metal extraction percentage from dilute aqueous sulfate media. Furthermore, different conditions such as temperature, pH and acid concentration of the feed solution will be examined. (AU)
