Analysis of Magnetic Mineral Types of Iron Sand at Sampulungan Beach, Takalar Regency Based on Magnetic Susceptibility Values

Abstract

Analysis on magnetic minerals of iron sand in Sampulungan Beach, Takalar Regency based on magnetic susceptibility value has been conducted. Iron sand was taken on 30 points and extracted using a rod magnet, then measured magnetic susceptibility using Bartington susceptibility meter MS2 with the MS2B sensor. Furthermore, types of magnetic minerals were analyzed based on the value of magnetic susceptibility. The results showed that the percentage of magnetic mineral was higher along the trajectory near residential areas. Magnetic susceptibility values ranged from 33932.62 x 10-8 m3/kg to 71829.96 x 10-8 m3/kg. Based on the value of magnetic susceptibility, the dominant type of magnetic mineral in Sampulungan Beach is magnetite (Fe3O4) of 76 wt.%. The high magnetite potential in Sampulungan Beach can be further processed to be used in the metal industry.

The Content of Magnetic Material in Black Sand of Yeh Gangga Beach

“…The iron oxide content that is often found in iron sand is magnetite, titanomagnetite, ilmenite, hematite, and maghemite. There are other follower minerals such as rutile (TiO2), ilmenite, shene, silica (SiO2), alumina, and others (Setiady et al, 2020;Purnawan et al, 2018;Vistarani et al, 2019;Begum et al, 2019;Moustafa, 2023;Abdel-Karim et al, 2017). Beside the high Fe content in iron sand, there are also elements C, Na, Mg, Si, P, S, K, Ca, Ti, V, Cr, Mn (Khwaja et al, 2015).…”
