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.
Silica sand mining business has more than doubled since 2009 because of the need for this particular type of sand, which is used in a process known as hydraulic fracturing. Wisconsin is one of the five states that produce nearly 2/3 of the nation's silica.
