Abstract
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. This method is based on measuring the degree of gasification of quartzites from a mixture with carbon reducing agents whose composition is calculated so as to ensure stoichiometry of the reaction SiO2s + Cs = SiOv↑ + COg↑.
