  • Silicon: mining and processing | Britannica

    The rock is melted in a furnace at 4,000 degrees and the silicon purified even further. The process itself is similar to that used in steel production and is why this molten rock is often referred to as metallurgical silicon. Yet the physical properties are not like those of a metal, they are instead like those of a semiconductor.
