How Is Silicon Obtained? | eHow
The Production of Pure Silicon. Pure silicon is produced by heating silicon dioxide along with carbon in an arc furnace at around 1900 degrees Celsius. The heat causes the oxygen in the silicon dioxide to split from the silicon and bond with the carbon. Hence, the outputs of this process are pure silicon, carbon monoxide and carbon dioxide.

The Silicon Mines - spacewhippet
Once we have a pile of SiO2 sand, we need to get rid of the O2 part, so we heat it to a badillion degrees (2000+ C.) By mixing the sand with carbon at these temps, the O will form CO2 and leave the Si behind. That gets us to ~98% purity, which is a good start, but we need 99.9999999% purity to make chips.
