摘      要：Identification of magnetite nanoparticles synthesized from natural iron sand with a chemical treatment that is by using thecoprecipitation method on temperature and heated spaces, using a pair of acids and bases, i.e. HCL as a solvent NH4OH and as its precipation. The Crystal structure, the percentage of elements, the particle size and properties of the magnetism material characterization by XRD, XRF identification testing, and permagraph. From the results obtained in the Analysis that the value of the percentage purity of Fe3O4 are derived from Natural Sands before Extraction is of 81.42%, and once on extract 86.73% increase to its purity. From the results of the analysis of properties of ferrite magnet to Fe3O4from sand iron retrieved the value of Saturation Magnetization (Ms) produced amounted to 0.29 T, or residual magnetization Remanence (Br) of 0081 T, and Coercivityy(Hc) amounted to 1.82 kA/m expected data analysis results may explain the comparison characteristics in structure and magnetic properties of material with a natural sand Fe3O4 Aldrich so it can be an additional related information value added (added value) the local SDA.
