“…Therefore, efforts are being made to obtain local iron sand in order to ensure the availability of magnetic minerals. The distribution of iron sand in various areas has been identified, including at Loji and Ciletuh Sukabumi beaches (Setiady et al, 2020), North Pringgabaya village, East Lombok (Safitri et al, 2020), Samas beach Bantul (Sismanto et al, 2017), Bubujung Tasikmalaya beach (Suwahyadi et al, 2021), Betaf Sarmi beach, Papua (Haryati et al, 2019), and iron sand in Sumbawa district (Nugraha et al, 2021).…”

Yeh Gangga Beach is one of the black sand beaches in the Tabanan district. The abundant black sand on this beach stretches along the shoreline with varying grain sizes. This black sand characterizes the specific surface composition as iron sand deposits with high magnetic mineral content. The very high need and use of magnetic minerals in various fields prompt a study of the magnetic mineral content in the black sand of Yeh Gangga beach.The magnetic material content was determined by the extraction method which was expressed in terms of mass fraction. The grain size distribution was determined by the sieve method using a sieve shaker consisting of six mesh numbers, namely 30, 100, 170, 200, 270, and 325.The density of magnetic materials was determined by the principle of mass and volume ratio. The magnetic susceptibility was tested by using a Bartington MS2B susceptibility meter. Meanwhile, the characterization of the elements and their oxides used non-magnetic methods, namely the X-Ray Fluorescence test.The research results show that the magnetic material fraction of Yeh Gangga black sand reach 84.84% with 58.39% of the grains having sizes in the range 150r ≥90 μm. The magnetic susceptibility value is 28.26 10-6 m3/kg with an Fe element content of 85.15% w. The hematite (Fe2O3) content reaches 81.69%. This magnetic material has a density of 1914.43 kg/m3.

“…The iron sands in Papua have begun to attract attention nowadays, in particular on the north coast of Papua. Our previous studies focused on the iron sand from the coastal areas in Sarmi Regency [12][13][14][15]. The natural iron sand in Sarmi revealed that hematite and magnetite mineral were dominant [13], and they could be useful as a concrete raw material for nuclear protective walls [14].…”

In this study, we investigated the mineral content and magnetic properties of river iron sand from Jayapura, Papua. The iron sand was collected from the Waimbow River in the Waibu District, whereas the bulk samples were extracted using a permanent magnet. The extracted iron sand was characterized using X-ray fluorescence and X-ray diffractometer to identify the elemental composition and structural phase. Meanwhile, the vibrating sample magnetometer was also applied to characterize the magnetic properties. The results show that the iron sand contains magnetite as a major mineral, with soft magnetic properties. The hysteresis curve shows that the iron sand has a high saturation magnetization of 27.8 emu/g, remanent magnetization of 2.34 emu/g, and coercive field of 21.3 Oe. These results also indicate that the iron sand formation in northern Papua was mainly due to lithogenic factors.
