INDIAN GEOGRAPHY

Detailed explanation-1: -Silica, commonly known as quartz, is the most common source. Silicon dioxide is also known as silica sand or quartz sand (SiO2). The most abundant component of the Earth’s crust is silicon compounds. Sand is the major mineral source of silicon because it is abundant, easy to mine, and relatively easy to process.

Detailed explanation-2: -Therefore, silicon is obtained from silica (quartz).

Detailed explanation-3: -The raw material for most silicon production is the mineral quartzite. Quartzite comes from ancient deposits of quartz sands that formed sedimentary deposits. Over time and with heat and pressure, these quartz sandstones were transformed into the metamorphic rock quartzite, which is at least 80% quartz by volume.

Detailed explanation-4: -Silica, commonly known in the form of quartz, is the dioxide form of silicon, SiO2. It is usually used to manufacture glass, ceramics and abrasives.
