Production of Ferro-Silicon – IspatGuru
The ideal reduction reaction during the production of Fe-Si silicon is SiO2+2C=Si+2CO. However the real reaction is quite complex due to the different temperature zones inside the SAF. The gas in the hottest zone has a high content of silicon mono oxide (SiO) which is required to be recovered in the outer charge layers if the recovery of Si is to be high.
Classification of quartzites by gasification from a ...
Considerable time is required for industrial tests to assess the utility of quartz and quartzites in the production of silicon ferroalloys. A relatively simple method of classifying quartzite with respect to the production of silicon, ferroalloys, carborundum, and carborundum-bearing reducing agents has been devised on theoretical principles and introduced in practice.

Quartzite - Wikipedia
02-02-2004 · Quartzite 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).
