Industrial minerals are non-metal and non-fuel mineral resources including, for example, crushed rock, gravel, clays, sand (silica), gypsum, bentonite, and barite. They are used in the construction of buildings and highways, in many industrial processes, and in a number of household products including toothpaste and sunscreen.

For each resident of our country, we use more than 24,500 lbs. of industrial minerals per year in the United States. Sand, stone, and gravel make up more than half of that amount. The rest are clays, salts, and other non-metals.[1] Industrial minerals are essential to thousands of everyday products including medicines, paint, ceramics, construction materials (from roofing to windows to insulation), ink, and paper coatings.

Geoscientists locate industrial mineral deposits, help determine how to mine them economically, help protect water and minimize environmental around the mine, and help reclaim disturbed land after mining.
