How Is Silicon Mined

Silica sand is also known as silicon dioxide, and as you've no doubt guessed from the name it's a compound of silicon and oxygen. That silicon is then treated with oxygen to remove impurities such as calcium or aluminium, leaving what's known as metallurgical grade silicon. That's up to 99% pure. How much silicon is in the earth? Almost 30 percent of Earth's crust consists of silicon ...
