silica sand is one of the non-metallic minerals found in abundance in Indonesia.

This sand is composed of silica grains (SiO₂) which generally come from quartz rocks that have undergone weathering or erosion.

Quality and Characteristics

Silica sand in Indonesia is famous for its good quality, with a high silica content. The color of silica sand varies from white to brownish, depending on the content of other minerals and the level of purity. The size of the silica sand grains also varies, from very fine to coarse grains, depending on the formation process and mining location.
