  • How silicon is made

    How silicon is made

    The Manufacturing Process The basic process heats silica and coke in a submerged electric arc furnace to high temperatures. High temperatures are required to produce a reaction where the oxygen is removed, leaving behind silicon. This is known as a reduction process. In this process, metal carbides usually form first at the lower temperatures.

    May 01, 2016 · Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as openpit, opencut or opencast mining and is only commercially viable if the deposit is loed relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
