An unknown number of silica sand mines produce silica sand for construction and agricultural uses. Silica sand mines producing frac sand may or may not process the sand onsite. Offsite processing plants that receive silica sand from various mining operations in Minnesota and Wisconsin are also found in Minnesota. How is it mined?

Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth''s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
