HOW WE MINE
We produce our Midwest Region deicing salt from underground mines in the U.S. and Canada, using both drill-and-blast and continuous mining techniques. We extract salt from each mine in rectangular “room” sections, leaving behind vast “pillars” of salt to support the mine structure. Our Goderich, Ontario, mine is the world's largest rock salt mine, serving customers around the Great Lakes and throughout Ontario and Quebec. Our mine in southern Louisiana serves customers along navigable rivers in the U.S. Both mines have extensive and consistent reserves with decades of remaining production.
We produce our West Region salt through solar evaporation, the oldest and most energy-efficient method of mineral production. At the Great Salt Lake in Utah, we draw mineral-rich brine from the lake’s most remote areas into a series of shallow ponds. The sun and wind evaporate the water in these ponds over a three-year span, leaving beds of naturally occurring, crystallized minerals. We gather these minerals and cleanse and process them to produce our products.
When you need salt, Compass Minerals delivers. Our extensive distribution network, coupled with our knowledgeable Sales and Customer Experience teams, helps you provide safer highways, streets and bridges during harsh winter weather in all major snow-belt regions.
