what is the process of mining silicon

Silicon dioxide

Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO2, most as "tooth powder". Manufactured or mined hydrated silica is used as the hard abrasive in toothpaste. Silicon oxide layers could protect silicon surfaces during diffusion processes, and could be used for diffusion masking....
