Extraction of Silica from Bengkulu Beach Sand using Alkali ...

of silica can be obtained by utilizing natural materials such as beach sand. In this research the solid-liquid extraction (leaching) method was used in three main steps. Bengkulu beach sand as precursors reacted with NaOH (alkaline fusion) at 95°C to form Na 2 SiO 3, then addition of HCl to form Si(OH) 4, and drying the silica gel becomes SiO 2

Five efficient methods of removing iron from silica

2021-1-15  Iron removal by acid leaching separation is based on the fact that quartz is insoluble in acid (except H, impurity minerals containing Fe can be dissolved by acid solution), so that the purpose of removing iron-bearing minerals from quartz sand can be achieved. The acid leaching method can not only remove iron-bearing minerals from quartz sand, but also remove non-metallic impurity minerals ...
