Abstract
Iron sand is one of the natural resources in West Sumatra that has not been optimally utilized. One of the potential locations to get this iron sand deposits is the coast of Kata. This study aims to analyze the content and size of the iron grains found on the coast of Kata Padang Beach, West Sumatera Province. Coastal sand samples are extracted using permanent magnets to separate magnetic and non-magnetic materials. Characterization of iron sand using Scanning Electron Microscopy with Energy Dispersive X-ray (SEM-EDX) and Vibrating Sample Magnetometer (VSM). The result of characterization using SEM-EDX shows that iron sand samples contain Fe and O elements derived from Phase Magnetite (Fe3O4). Keywords: iron sand, magnetic materials, SEM-EDX, VSM
Highlights
INTRODUCTIONSand is only used as building materials, whereas the sand contains many valuable minerals containing iron, titanium and other elements that can be utilized for industrial materials
Sand is an abundant natural material available in Indonesia
Ref [11] found that the iron sand content in sand found in Air Tawar Padang Beach is quite high (41%) [12]
Summary
Sand is only used as building materials, whereas the sand contains many valuable minerals containing iron, titanium and other elements that can be utilized for industrial materials. Iron sand in nanopedic sizes has many application opportunities in industry, electronics and medical [5], Earth magnetism studies [6,7] and defence as anti-radar materials [8]. Ref [11] found that the iron sand content in sand found in Air Tawar Padang Beach is quite high (41%) [12]. In this research use iron sand from Kata Beach, Sumatera Barat Indonesia with the aim to know the composition of iron sand especially mineral content and Fe grain size with High Energy Milling (HEM)
