Silicon dioxide - Wikipedia

Certain deposits of silica sand, with desirable particle size and shape and desirable clay and other mineral content, were important for sand casting of metallic products. The high melting point of silica enables it to be used in such applications such as iron casting; modern sand casting sometimes uses other minerals for other reasons.


Accordingly the embodiments herein provide a method of preparing Silicon (Si) from sand (SiO 2 ).The method includes obtaining sand particles with size less than 50 microns. The sand particles are obtained by washing the sand with an alkali and Hydrochloric (HCl)
