Research on the magnetic susceptibility and size distribution of magnetic nanoparticles of beach sand Sungai Suci Bengkulu has been done. The samples were synthesized using ball milling. Iron oxide and non-iron oxide particles of ball milling products were separated using Neodymium Iron Boron (NdFeB) magnets. Magnetic induction measurement on ball milling products has been carried out using Pasco magnetic probes. Product of NdFeB was milled for 60 hours using milling ball combination of 0.5, 0.7 and 1.5 cm in diameter and the product is called BM1 product. This product was divided into three parts called BM1A, BM1B and BM1C then milled separately for 40 hours using milling balls with diameter of 0.5, 0.7, 1.5 cm, respectively. The products of this ball milling are called BM2A, BM2B, BM2C. The results show that magnetic susceptibility of BM II products increases with increasing milling ball size that is 9215.48 × 10 -5 , 10097.64 × 10 -5 and 11056.86 × 10 -5 for milling ball size of 0.5, 0.7 and 1.5 cm, respectively. The particle size distributions of the samples were determined using the Particle Size Analyzer (PSA). The results show that the distribution of particle size at a percentage of 10% is 0,40 µm and 1,30 µm for BM2A and BM2C, respectively.

“…Iron sand is a magnetic material that has the properties of a ferromagnetic material (Gunanto et al, 2018;Karbeka et al, 2021;Yulia and Erwin, 2019). Iron sand has several mineral contents such as hematite (𝛼-Fe 2 O 3 ), maghemite (𝛾-Fe 2 O 3 ), ilmenite (FeTiO 3 ), silica (SiO 2 ), magnetite (Fe 3 O 4 ), alumina (Al 2 O 3 ) and rutile (TiO 2 ) (Nengsi et al, 2016;Sihombing and Amiruddin, 2020;Susilawati et al, 2019). In addition, many unnecessary minerals (gangue) such as K, C, Mg, Na, Si, Al and Ca elements attached to iron ore can reduce the magnetic properties of iron sand.…”

The synthesis and characterization of Fe2O3 from Iron Sand of the coastal sea of Cidaun Beach - South Cianjur using the coprecipitation method has been carried out. The purpose of this research was to identify the crystal structure, magnetic mineral content, and magnetic properties of iron sands. The characterizations used in this research are X-Ray Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) and Vibrating Sample Magnetometer (VSM). Based on the XRD results, it shows that the iron sand sample produces multi-phases, namely hematite (????-Fe2O3), maghemite (????-Fe2O3) and ilmenite (FeTiO3). SEM-EDX results indicate that the iron sand samples have an average particle size of 12.396 ????m. VSM results indicate that the iron sand sample is soft magnetic (ferrimagnetic) with saturation, remanence and coercivity values of 47 emu/g, 1.53 emu/g and 102.97 Oe, respectively.

“…Similarly, Tiwow et al found that iron sand from Bontokanang village had a Fe element percentage of 66.7%, while iron sand at Tanjung bayang beach had a Fe element percentage of 79.56%. A greater Fe rate is advantageous for synthesizing Fe3O4 nanoparticles[16],[17]..Figure 1. Research flow diagram Figure 2.…”

This research aims to produce Fe3O4 magnetic nanoparticles-based Taman River sand as the raw material through coprecipitation. The Fe content percentage in the Taman River sand after separation was characterized using XRF testing. The lattice parameters and crystal size of the samples were tested using XRD. The nanoparticles' morphology, structure, particle shape, and elemental content were characterized using SEM-EDX. The magnetic properties and magnetic saturation values were tested using VSM. XRF testing results on the iron sand showed a Fe content of 84.72%. The synthesis resulted in a brNownish-black Fe3O4 nanoparticle powder that a permanent magnet could attract. Based on the XRD results, the Fe3O4 nanoparticle powder peaks were obtained at X-ray diffraction pattern angles of 2θ: 21.44°, 35.38°, 41.74°, 50.78°, 63.36°, 67.70°, and 74.66°, indicating the presence of Fe3O4 nanoparticles. The crystal structure formed was cubic with lattice parameters a = b = c = 8.331 Å and a crystal size of 18.43 nm. SEM-EDX results showed an average particle size of 25-30 nm. VSM results indicated that the Fe3O4 sample had a saturation magnetization (Ms) of 27.36 emu/g, a remanent magnetization (Mr) of -0.01 emu/g, and a coercive field (Hc) of 0.01 T.
