Whenever you work on a project that requires cutting, grinding or chipping concrete, you will make concrete dust. The primary ingredient of concrete dust is crystalline silica. According to Amicus, "For many years, it has been known that breathing in fine dust containing crystalline silica can cause lung damage (silicosis)."

The removal of iron from silica sand by acid leaching is based on the fact that silica sand is insoluble in acid (except HF), and the impurity minerals containing Fe can be dissolved by acid solution, so the iron minerals can be removed from silica sand. After flotation, the purity of silica sand can reach 99.5-99.9%.
