“…2 shows bragg diffraction peaks which are thought to consist of multi-phase. Phase identification refers to the results of Yamanaka's research, which are ilmenite, hematite, and ferrosilite phases respectively [12]. In Table 2 it is shown that the mineral phases contained in Ilmenite-type iron sand rocks are ilmenite, hematite, and ferrosilite minerals.…”

Synthesis and characterization of α-Fe2O3 nanoparticles were obtained from extraction of ilmenite iron sand with coprecipitation method and to obtain α-Fe2O3 nanoparticles, high energy milling (HEM) was used. Surface morphology and identification of the elements contained in the sample were analyzed using scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). For phase analysis and crystal structure, X-ray diffractometer (XRD) was used. Moreover a vibrating magnetometer sample (VSM) was used to characterize its magnetic properties, while tunneling electron microscopy (TEM) was used for particle size characterization. Ilmenite-type iron sand has a diverse particle shape with a size of more than 100 μm with ilmenite (FeTiO3) mineral content of about 64.7%. The results of extraction using coprecipitation method with sintering 750 °C, obtained hematite α-Fe2O3 material which has not been saturated to an external magnetic field of 1 tesla, the magnetic remanent value (Mr) is about 0.8 emu/g and the coercivity field value is Hc around 773 Oe. The average size of hematite α-Fe2O3 particles after being milled 50 hours is between 15-30 nm with a cube-like shape.

“…Beach placer is internationally recognized as a strategic mineral due to its multi-metallic content [3,4]. Beach placer is highly weathered, with a large Fe 2 O 3 /FeO ratio and high Ti content, while Ti-bearing material often exists in the form of ilmenite (FeTiO 3 ), ulvospinel (Fe 2 TiO 4 ), and titanium magnetite (Fe 3−x Ti x O 4 ) [5,6]. Due to the close symbiosis of Fe and Ti elements from beach placer, the methods of separating them efficiently have become a hot issue in current research [7].…”

The effect of borax on the reduction characteristics of Indonesia beach placers was investigated. The effect of grinding alkalinity on the magnetic separation of the reduced sample was also studied in this paper. The mineral phase transformation, microstructures of reduction, and magnetic separation products were analyzed to reveal the enhanced separation mechanism of titanium and iron in beach placer. The borax could effectively improve the metallization rate and the growth of iron grains in a reduced sample. When 3% borax was added to the reduction process, the metallization rate of the reduced beach placer reached 95.64%, and the metal iron grains grew to about 50 μm. Adjusting the grinding alkalinity could prevent the metallic iron from being oxidized and promote the monomer dissociation between mineral particles. The iron powder concentrates with 94.07% total Fe and vanadium-rich titanium slag with 36.32% Ti were obtained by grinding magnetic separation as the grinding alkalinity pH was 13.
