Apatite ore from Lao Cai province (Vietnam) has large reserves and low cost which was purified by a simple chemical method. one were characterized the molecular structure, phase component, specific surface area, element morphology IR, XRD, BET, EDX, SEM methods. The IR result shows both materials have functional groups of fluorapatite such as PO43- F-. XDR EDX confirm that main component is flu...
