Industrial Minerals

Ohio's geology is rich with source materials used in numerous industries and in making a variety of everyday products. A robust history of industrial minerals extraction has driven the state's economy since before statehood in 1803. Today, Ohio continues to be a leading producer nationally of several commodities, including limestone, dolomite, sandstone, and conglomerate; sand and gravel; clay and shale; and salt.

The ODNR Division of Geological Survey compiles production and economic data, submitted by the state's industrial mineral operators, to produce the Annual Report on Ohio Mineral Industries. The report is available as a free download and includes a map of active operators. 

Most Recent Ohio Economic Geology in Brief:  2018

The total tonnage of coal and industrial minerals produced in Ohio during 2018 was 113,037,754 tons or approximately 9.7 tons per capita. The total value of coal was $379,576,872 in 2018; the value of oil and gas was $8,374,209,575; and the value of all industrial minerals was $1,183,675,048 in 2018. The combined value of fuel and nonfuel minerals produced in Ohio during 2018 was $9,937,461,495 or approximately $850 per capita.

Reported and estimated total direct employment in the extractive industries of Ohio in 2018 was more than 10,000 people. Industrial-mineral production decreased for all commodities except limestone and dolomite. The total value of nonfuel industrial minerals exceeded $1 billion for the fifth straight year. In 2018, production for the leading commodity of limestone and dolomite was up 4.7%, while the second leading commodity of sand and gravel was down 2.1%, and the third leading commodity of coal was down 6.4% from 2017 values. In 2018, clay, shale, salt, and sandstone and conglomerate commodities production were all down by double digit percentages.

Total values include reported and estimated values. Some operations reporting sales did not report a value for those sales. A countywide- or statewide-average price per ton was calculated for each industrial mineral commodity based on sales for which the value was reported. A countywide average price per ton was calculated for coal based on (1) sales for which the value was reported and (2) method of production. These calculated averages were used to estimate the value of the sales for which the actual values were not reported.
