Rekomendasi Pemanfaatan Pasir Kuarsa Desa Latsari, Kecamatan Bancar, Kabupaten Tuban, Jawa Timur Berdasarkan Karakteristiknya

Abstract

Quartz sand is an industrial mineral in high demand. Indonesia must maximize this opportunity, as the potential of silica sand is vast, particularly in Latsari Village, Bancar District, Tuban Regency, East Java. Analyzing the characteristics of quartz sand is crucial to determine its potential uses. In this study, six quartz sand samples were collected and analyzed for grain morphology, size distribution, and geochemical composition to evaluate their characteristics and suitability be used according to standard specifications. The quartz sand’s average grain size is classified as medium sand (0.25-0.5 mm) and has a subangular shape, which means nearby its source rock. Geochemically, quartz sand in research area consists mostly of silica oxides (63.37%-92.09%) and smaller amounts of iron oxides (1.02% - 10.74%), and aluminium oxides (4.67% - 25.47%), which negatively correlate with silica content. Based on its silica and oxide content, the use of quartz sand in the research area is recommended for producing refractory bricks for the casting industry with notes sample need purification process to remove impurities and increase silica content.
