what is the process of mining silicon
Mining silicon to make silicon-based cells is an expensive process that emits a lot of carbon dioxide. Silicon-based panels are well established in the market, but are rapidly being replaced by more efficient thin-film technologies. In general, silicon is less cost effective, but the panels are more space efficient.

Description. Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2 ). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
