  • processing of quartz silica - apemonaco.org

    Currently, the most popular way of purifying metallurgical silicon is through the Siemens process. However, this process is very expensive, and it would be more favourable to upgrade the metallurgical silicon using high purity quartz. Processing Metallurgical grade silicon (MG-Si) is produced through the reduction of quartz with carbon.
