    Mar 22, 2016 6) SAND AND SILICA SAND Silicon (Si) is the 2nd most abundant element in earth’s crust. Commonly found in its oxidized form (SiO2). Sand is a naturally occurring granular material comprised of finely divided rock and mineral particles. Sand is transported by wind and water and deposited in the form of beaches, dunes, sand spits, sand bars.This study was aimed to increase granite's silica content using the leaching process with HCl concentration variation. The granite used in this study came from Lematang, South Lampung. This study aims to determine the effect of variations in HCl concentration, particle size, and rotational speed on the crystalline phase and chemical elements formed in the silica product produced from granite.
