How is Industrial Sand Produced?
Industrial sand production begins with mining. Some ore deposits are
mined by scooping unconsolidated material, some require blasting and crushing
hard rock formations in quarries, and some rely on dredging below the
water table. Once extracted, the work has only begun. Additional steps
include washing, processing to remove impurities, draining, drying, screening
to segregate the sand grains by size and, at some plants, grinding and
packaging. Most industrial sand is shipped to industrial customers in
bulk by truck or rail. The mining and processing operations are capital
intensive, requiring multi-million dollar investments for machinery and
other equipment. Thus, the industry must focus on long term commitments
and planning for industrial sand operations to be viable. NISA member

community involvement, and proper environmental stewardship.
