“…Another category of coastal sand mining for metals is of iron sands—which have heavy concentration of iron ores. Iron sands have diverse industrial applications some of which are in steel manufacturing, absorbents for removing heavy metals such as arsenic from water, in the pigment industry, as magnetic sensors, and magnetic fluids (Satria et al., 2021).…”

Coastal sand mining for metals involves extraction of heavy mineral sands (HMS), which are sedimentary deposits of dense minerals that accumulate in coastal environments. HMS are localized concentrations of ores such as ilmenite, rutile, leucoxene, and iron, which are sources of metals such as titanium, zircon, iron, sillimanite/kyanite, staurolite, monazite, and garnet. The applications of these metals range from everyday products such as ceramics, paint, and pigments, as well as technologically advanced applications in the airline, shipbuilding, medicine, and defense industries.HMS extraction implies strip mining of coastal areas, which are often unique biodiversity ecosystems, or fragile ecosystems built up on sandy soils or dunes. The loss of such spaces has impacts such as loss of biodiversity and habitats, salt-water intrusion into agricultural lands and increased exposure to sea level rise. As a result of the serious ecological and socioeconomic transformations at such extraction frontiers, these operations cause resistance movements across the world. This article identifies and documents 24 cases of resistance against such operations. It presents the first comprehensive database and analysis of HMS related ecological distribution conflicts.

“…Indonesia's Iron sand abundancy is deposited in several areas such as Sumatra, South of Jawa, Sulawesi, Maluku, and Papua that possibly produced from volcanic eruption and erosion of older rock [1]. In 2020, Ministry of Energy and Mineral Resources of the Republic of Indonesia reported the amount of Iron sand resources in Indonesia is 2.9 Billion tons and supply 1.7% of world Iron sand that the iron content was less than 12% [2].…”

High potency of Indonesian iron sand can be optimized by transforming to valuable iron oxide product namely Hematite (α-Fe2O3). Hydrothermal synthesis was carried out to transform iron oxide phase to hematite that can be analyzed by x-ray diffraction method. Utilization of ion sand as raw material produced multyphase in product reaction, while the usage of Fe(OH)x that extracted from iron sand attained high purity of hematite. The best conditions of reaction were at 160 oC for 24 h. Higher temperature and longer time reaction transformed α- α-Fe2O3 to be γ-Al2O3 and Fe3O4 as more stable phase.

This study aims to analyze silica's morphological characteristics and electrical properties based on the river and coastal sand. Iron samples were taken from Sompang river sand, East Lombok and Coastal Sand from Gading, Mataram City. The silica was synthesized using the sol-gel method with a sintering temperature variation of 100 to 175 ℃. Morphological characteristics samples analysis was done using SEM-EDX. The electrical properties of iron sand included measuring the dielectric constant using the parallel plate method. Furthermore, the resistivity was measured using the two-point probe method. In the silica-based on river sand sample, the resistivity value was inversely proportional to the sintering temperature. In contrast, the resistivity value of silica based on the coastal sand sample was directly proportional to the sintering temperature. Silica-based on river sand has a resistivity of about 7.1'104 Wm at a sintering temperature of 100℃ and 3.5'104 Wm at a sintering temperature of 175℃. Silica-based on river sand has a resistivity of about 1.8'104 Wm at a sintering temperature of 100℃ and 7.1'104 Wm at 175℃. This research is a preliminary study on the electrical properties of natural sand-based silica to improve understanding of the physical properties of silica to be used in technological applications, such as sensors. Furthermore, the dielectric constant value in the river sand sample was directly proportional to the sintering temperature. However, the dielectric constant in the coastal sand sample was inversely proportional to the sintering temperature. Silica-based on river sand has a dielectric constant of about 1.02'102 at a sintering temperature of 100℃ and 1.18'102 at 175℃. Silica-based on coastal sand has a dielectric constant of about 1.97'102 at a sintering temperature of 100℃ and 1.15'102 at 175℃.
