Silica sand was milled by High Energy Milling in order to reduce the size into powder form. Effect of milling time shown the content of sodium and silicon is increased in sodium silicate solution obtained from various times of silica sand milling 30, 60 and 90 minutes, respectively which is reacted with sodium hydroxide 8 M.
