Quartzite – Wikipedia

Quartzite (from German: Quarzit) is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe 2 O 3).

process for production of silicon metal from quartz

Silicon metal and ferrosilicon production – Silicon (Si) is produced from quartz (SiO2) through an apparently very simple chemical reaction of reduction: Quartz + Carbon à Silicon + Carbon Dioxide. SiO2 + C à Si + CO2 This reaction requires the massive use of electricity, which gives to the transformation process its name of electrometallurgy.
