Industrial minerals refers to geological deposits that can be mined for profitable commercial and industrial uses, as opposed to minerals used as gems, or as fuel (oil, gas, and coal).

Ohio has a long history of industrial mineral production, dating back to before settlement by American and European migrants.

Sand, gravel, limestone and other rock products are used in the construction industry. Salt keeps wintry roads free of ice and many other minerals are essential to our national prosperity.

Ohio's Industrial Minerals:

• Limestone and Dolomite
• Sand and Gravel
• Sandstone and Conglomerate
• Clay and Shale
• Salt
• Gypsum - Since 2005, no longer produced in Ohio
