Question

From which mineral silicon is obtained?

Answer 1

1. On Earth's crust,Silicon is the second most abundant element having $27.7\mathrm{\%}$ by mass.
2. It is found as silica and silicates in nature, but the most common source is silica which is also known as quartz.
3. Being easy to mine and also relatively easy to process, sand is one of the major mineral sources of silicon.
4. Another source of silicon is a metamorphic rock called Quartzite

Therefore, silicon is obtained from silica (quartz).
