Apr 18, 2017· 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.
The selection of quartzites most suitable for the production of ferrosilicon is realized by way of time-consuming industrial trials or laboratorial studies of, among others, the ability of the silica contained in quartzite to form silicon carbide with a selected reducer. Under industrial conditions, the basic criterion for the evaluation of the suitability of a raw material for the production ...
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).
