Not All Salt Is Created Equal

Did you know, the United States produces 42 million tons of salt in a year? (2019, United States Geological Survey, USGS).  Within all that quantity, there is quite a variation in quality. Let's learn more about where all this salt comes from, how it is produced, and the physical and chemical properties that prove not all salt is created equal.

Not All Salt Is Created Equal

Location, Location, Location

Salt can't be produced just anywhere. The right geological and meteorological conditions must be met. For this reason, 92% of U.S. salt is produced in just 7 states.

Salt is produced or harvested differently depending upon the location.

Mined Salt

Areas that are fortunate enough to contain subterranean salt deposits can mine their salt. These deposits are the remains of ancient sea beds, where excess minerals fall out of solution and collect on the seafloor. Mined salt will usually contain other minerals within the salt which expands its mineral profile, enhances its taste, and changes its color.

Solar Evaporated Salt

For coastal areas with little rainfall, solar evaporation can be used. Fields of saltwater are left to evaporate until salt crystals remain behind to be harvested. Some inland locations pump water into subterranean salt deposits, and bring the liquid salt brine to the surface for evaporation. Solar evaporation produces traditional white salt (sodium chloride). Creating liquid brine for evaporation does alter the salt’s chemical and physical properties from its natural form.

Vacuum/Open Pan Salt

Some locations have either too much precipitation or not enough access to sunshine for solar evaporation. These operations pump liquid brine into large pans to boil off the water, leaving white salt crystals behind for harvesting. As with solar evaporation, the process of dissolving and evaporating changes the salt’s physical and chemical makeup from its natural state.

The Redmond Mineral and Clay Deposit

Few locations contain the richness found at the Redmond mineral deposit in central Utah. The Earth has endowed this deposit with special chemical and physical properties, which can be discovered in its unique geological history.

History of the Redmond mineral and clay deposit

Early Jurassic Era

About 200 million years ago, during the early Jurassic, the Sundance Sea extended from the western coast of modern day Canada down into what is now the United States. Over time, this ancient seabed became a rich collecting ground for a wide profile of rare earth minerals. As the Sundance Sea retreated, these minerals hardened and crystallized.

Early Paleogene

About 60 million years ago, a volcanic eruption deposited ash over the Redmond mineral deposit. This layer of ash formed a natural, protective cap which further preserved the minerals below. The volcanic ash weathered to become a nourishing layer of bentonite clay. Because clay particles naturally attract and retain ions and nutrients from their surroundings, the Redmond clay deposit became imbued with the rich, deep sea minerals in its environment.

Central Utah, 1958-1960s

With their hand forced by a prolonged drought, Milo and Lamar Bosshardt abandoned their farming pursuits. The brothers knew Native Americans had once harvested salt from the area, and began hand harvesting salt from their land to provide for their families.

Local governments began to notice that the special mineral salt from Redmond, Utah melted ice and snow more effectively than traditional white salt. The Bosshardt brothers began marketing Redmond’s mineral salt as a premium road deicer, and Ice Slicer was born.

Modern Day Redmond, Utah

The Redmond mineral and clay deposit has become a bustling operation for the ever expanding Redmond family of products. Today, many industries enjoy our profile of over 60 trace minerals.

The Redmond family of products

Redmond is proud of our special geological history, and takes our environmental stewardship seriously. Our mine and its facilities are 99% powered by solar energy and we love to offer all natural products to nourish the world from the ground up.
