“…Pasir silika telah banyak dimanfaatkan sebagai bahan utama pembuatan gelas dan kaca serta bahan baku pembuatan sel surya. Silika dan kalsium karbonat telah dikembangkan sebagai bahan nanokomposit untuk material keramik dan aplikasi di dunia industri yang berkaitan dengan produk farmasi, katalis dan pengembangan adsorben yang bersifat magnet [9][10][11][12]. Oleh karena itu, penelitian pada pasir tiga warna Pantai Puntaru akan memberikan kajian mineral yang terkandung di dalamnya.…”

Puntaru beach is famous for its three-colored sand that is mixed into one of them reddish-brown, black, and white sand. Research on the mineral composition of the tricolor sand has been conducted so that the use of three-colored sand is still done traditionally. This study aims to obtain information on the silica content and other mineral compositions of the three-colored sand of Puntaru Beach as initial data for further development. The three-color sand preparation process is carried out by the method of milling / crushing sand samples then sieving and washing with H2O. Stages of characterization of silica in three-colored sand were carried out using X-ray fluorescence (XRF), X-ray powder diffraction (XRD), and Fourier-transform infrared (FTIR). The analysis showed that the percentage of Si was the most dominant 45.28%, followed by Fe 25.94% and other minor elements. XRD results show that the three-colored sand contains quartz mineral (SiO2) identified at the main peak with 2 with in the 24.34 ° area. The black color of the sand is influenced by Fe content of 25.94% with hematite metal oxide (Fe2O3) 15.80% and reddish-brown influenced by the presence of sulfur (3.25%) in the form of mineral SO3 4.32%.

“…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].…”

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]. Interestingly, the magnetic extract of iron sand from the Tor river estuary showed a magnesioferrite (MgFe2O4) mineral with a higher mass-specific magnetic susceptibility value of 2.7  10 -4 m 3 /kg and a superparamagnetic behavior, suggesting a widespread application in microwave devices.…”

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.
