Iron sand is one of the abundant natural resources in Indonesia, especiallyon the south coast of Cidaun; West Java which is the basic material forbuilding and metal industry. Iron mineral content is generally metal oxide suchas magnetite, hematite and silica/quartz. Sand with iron content used in thisstudy is derived from beach sand Desa Kertajadi, Kecamatan Cidaun, KabupatenCianjur, Jawa Barat. Then mass of 2 kg sand was separated using a magneticseparator in order to obtain magnetic and nonmagnetic mineral content. Afternine rounds of separation takes two different types of samples that are noseparation sand (TS) sample and concentrate in the third separation (S3)sample. The sample is then examined by X-Ray Diffraction (XRD) measurement andanalyzed quantitatively using MAUD software to determine the content of Fe3O4(magnetite) by using the Rietveld refinement method from XRD data. As theanalysis result, the magnetite content contained in iron sand is countedquantitatively for each different sample. For iron sand samples (TS) yielding a24.27 percent of magnetite and a third concentrate separation sample (S3)yields 61.98 percent.
