Composition of Lean Apatite Ores from the Laokai Deposits

Аннотация

X-ray powder diffraction and X-ray fluorescence analyses of lean apatite ores from the Laokai deposits were performed. The test sample was divided into 11 fractions, each being analyzed for phosphorus and the major associated impurities. The chemical composition of the lean apatite was found to be virtually independent of particle size, thereby the primary beneficiation of the raw material being excluded.
