Abstract


In the industrial world, silica is widely used, such as in the tire, rubber, glass, cement, concrete, ceramics, textiles, paper, cosmetics, electronics, paint, film, toothpaste, healthcare, and other industries. The commercial value of silica determinant by its purity. In this study, silica extraction from minerals taken from the Kokap area, Kulonprogo, was carried out. The extraction of silica from minerals aims to increase silica content. In this research, the effect of NaOH concentration and particle size in silica extraction from minerals was studied. The variation in particle size is 100 mesh and 150 mesh, while the variation in NaOH concentration is from 0.5 N to 5 N with a difference in concentration of 0.5 N. The product of this research is silica gel. The experimental results show that the greater the NaOH concentration, the greater the silica that can be extracted. When viewed from the particle size, a smaller particle size results in a larger conversion. The largest extract was obtained at a particle size of 150 mesh with a concentration of NaOH 5 N, which is 4.73 grams of silica gel or 1.6979 grams of silica.
