Abstract

The extraction and concentration of rare earths from leach liquor of APATITE CONCENTRATE of CENTRAL IRAN were investigated using combined precipitation and SOLVENT EXTRACTION methods. Precipitation was carried out to remove undesirable ions and SOLVENT EXTRACTION method using tri-n-butyl-phosphate (TBP) as an extractant was employed to separate and concentrate RARE EARTH ELEMENTS. The XRD studies demonstrated that fluro-apatite, ancrite and calcite are the comprising minerals in the examined mica (apatite) and fluro-apatite is the predominant mineral. The amount of rare earth element-oxides including Y, Ce, La, Pr and Nd were determined by means of X-ray florescence (XRF) analysis. The other chemical composition of apatite consists of: SiO2, CaO, Fe2O3 and P2O5. First, acid leaching operation was carried out by using nitric acid. The analytical investigation of the obtained leach liquor indicated that interfering ions include: Fe (II), Mg (II), Ca (II), S (IV), P (V) and F (I). The precipitation studies confirmed that the process was rapid and highly efficient to remove the interfering ions without removing RARE EARTH ELEMENTS. The effect of different variables such as extractant concentration, nitric acide concentration, temperature, contact time and Vorg./Vaq. were investigated and the optimum conditions for separation of lanthanides by TBP were determined. Selective stripping of lanthanides from the loaded organic phase were studied using nitric acid. The separation of rare earths by TBP was observed to be significant and more than 90 percent of RARE EARTH ELEMENTS were extracted. The thermodynamic functions of lanthanides extraction process have been calculated.
