where the silica iron is extracted

What is Silica?

Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application. Silica sand may be produced from both unconsolidated sands and crushed sandstones.
